Pontine Marshes
The Pontine Marshes ( in the Monti Lepini.
The former marsh is a low tract of mainly agricultural land created by draining and filling, separated from the sea by
Further southward along the coast as far as Minturno is another stretch of former coastal marsh called the South Pontino, the largest section being between Terracina and Sperlonga, as far inland as Fondi. It was part of ancient Latium adiectum and still belongs to Lazio. Bordered by the Aurunci Mountains, this land is mainly reclaimed, as well, but the more frequent incursion of hills permitted more dense settlements. Leaving Terracina, the Via Appia crosses it, as well.
The marsh was an extensive alluvial plain at about sea level (some above, some below) created by the failure of the streams draining the mountains to find clearly defined outlets to the sea through the barrier dunes.[4] Above sea level, it was a forested swamp; below, it was mud flats and pools. Sparsely inhabited throughout much of their history, the Pontine Marshes were the subject of extensive land reclamation work performed periodically. The tribe of the Volsci began with minor draining projects in the vicinity of Tarracina in connection with their occupation of it in the pre-Roman period.
The road proved difficult to keep above water. Under Augustus, a compromise was reached with the construction of a parallel canal. The part of the marsh above sea level was successfully drained by channels, and new agricultural land of legendary fertility came into being. Whenever the channels were not maintained, the swamp reappeared. Meanwhile, frequent epidemics of malaria at Rome and elsewhere kept the reclamation issue alive. Under Benito Mussolini's regime in the 1930s, the problem was nearly solved by placing dikes and pumping out that portion of the marsh below sea level. It continues to need constant maintenance. Italian confidence in the project was so high, the city placed by Mussolini in 1932 in the center of the marsh, Latina, became the capital of a new province, Latina.
Geology
The Agro Pontino geologically is one of four geomorphic divisions of a somewhat larger area, the Pontine Region, also comprising the Monti Albani, the Volscian Mountains and Monte Circeo; in short, all of Roman Latium.[6] The marsh itself was located in Latium Novum, the eastern part of the region, which the Romans removed from the sovereignty of the Volsci. The two terms create some confusion in the literature, as the region was often heavily settled, but the marsh supported no resident population.
Pliocene
The underlying landform is a horst–graben, in which expansion of the crust causes a section to drop, creating a rift valley. Underneath the marsh is such a valley, while the steeply-sided Volscian Mountains and the floor under the outer dunes are the corresponding horsts. The graben was formed over a period approximated by the end of the Pliocene about 2.588 million years ago. The natural outcome of this graben topography was the creation of outer barrier islands and a lagoon that gradually filled with runoff sediment transported from the mountains.
Pleistocene
The rift valley remained a depression in the Tyrrhenian Sea for about two million years and then in the Tuscolano-Artemisio phase, dated 600–360 thousand years BP, a series of volcanic changes began leading to the current landform: the first four eruptive cycles of a new volcano in the vicinity of the Monti Albani, which spread pyroclastic rock and formed a caldera.[6] In the Campi di Annibale phase, 300-200 thousand years BP, a stratovolcano formed in the caldera. Approximately contemporaneously, in the Middle Pleistocene, 781-126 thousand years BP, beds of sand and clay, termed the Latina Complex, appeared above sea level over the outer karst, enclosing a lagoon.[7] The beaches survive at the Latina Level from about 560 thousand years BP.
The Tyrrhenian II transgression of ocean water into the lagoon left the Minturno level and complex, a dune barrier of about 13 m (43 ft), dated 125–100 thousand years BP.[8] Behind the beach, deep peat and clay deposits alternating with alluvial sediments evidence the lagoon. It was deepest at the Terracina end diminishing to the surface at Cisterna, where beds of travertine, sand fused by volcanic activity, reach the surface. At this time, Latium Vetus had been formed as a volcanic land mass, while Latium Novum was a lagoon, the future marsh.
The Tyrrhenian III transgression left the Borgo Ermada Complex and Level, about 90 thousand years BP. It consisted of elongated sand ridges parallel to the shore, 8 to 15 m (26 to 49 ft) high. During the regression phase, fluvial incisions indicate by then at very latest, the lagoon was totally enclosed. After it drained, aeolian (wind-driven) sand covered the notches.
At around 22 thousand years BP, the volcanic complex became active for the last time, erupting in hydromagmatic explosions that created the beds of Lakes Albano and Nemi, both crater lakes.
Holocene
The most recent beach, the Terracina Complex and Level, which began the Holocene about 11700 years BP, was a single ridge behind which clay, peat, and peaty clay were being deposited at sea level. No land was yet above it. The region was a shallow lagoon interspersed with marshland. Fluvial incisions in the beach let out the excess water, which was brackish and contained salt-water mollusks, leading to the question of where the excess water came from and why alluvial fans had not buried the region. The answer is in the composition of the Volscian Mountains, which are limestone, porous, and excessively cracked and faulted. All but the heaviest rainfalls sink into the rock only to appear as a large volume of spring and groundwater at the foot of the mountains. Transport of sediment was minimal. In one estimate, 20 m3/s (710 cu ft/s) flow from springs over a distance of 20 km (12 mi).[5] In another estimate, 80% of the rain falling on the Monti Lepini is absorbed, with a single spring at Ninfa exuding 2,000 L/s (71 cu ft/s).[6] These facts explain why the main fill of the lagoon is peat, silt, and clay, and not thicker-grained alluvial deposits, and why it took so long.
Alluvial deposits known as the Sezze Fan began about 4000 BC in the marsh below

The geographers and historians of the early
"In front of Tarracina lies a great marsh, formed by two rivers; the larger one is called the Aufidus (Ufente). It is here that the Appian Way first touches the sea ... Near Tarracina, as you go toward Rome, there is a canal that runs alongside the Appian Way, and is fed at numerous places by waters from the marshes and the rivers ... The boat is towed by a mule."
In Strabo's view,
is notable for what it does not say, which is the names and locations of the cities. Many more than 24 Roman settlements were built in the marsh, but it is not possible to find 24 of the size of Terracina or Antium without counting Latium Vetus or the coastal lands south of Terracina.
According to Plutarch, Julius Caesar had ambitious plans for the marsh, which if realized or realizable would have diverted the Tiber through it:[21]
"During the expedition [a planned campaign around Europe] he intended ... to receive the Tiber immediately below the city in a deep cut, and giving it a bend toward Circaeum to make it enter the sea by Tarracina, ...besides this he designed to draw off the water from the marshes about Pomentium and Settia, and to make them solid ground, which would employ many thousands of men in the cultivation ..."

Pope Leo X, a Medici, proposed to finish the project but was opposed by the Duke of Sermoneta over the fishing rights. In 1514, he decided to drain the region around Terracina instead, assigning the task to his brother Giuliano de Medici, commander of the papal army. The Medicis would retain all reclaimed land. In 1515, Giuliano hired Leonardo da Vinci to design the project. It provided the Ufente River with outlets through the Canale Giuliano and Canale Portatore. Giuliano died in 1516, and the city of Tarracina combined with Sermoneta and Sezze to halt work, over the issue of property rights. The people of the marsh were not going to allow the Medicis to take their land.[23]
Popes
The ambitious Sixtus V also made unsuccessful attempts at reclamation of the area and died of malaria after a visit to the Pontine Marshes.

20th century
In 1928, the population of the marshes was 1,637. They were people who lived in shanties across the fields, herded, practiced agriculture, and were in poor health most of the time. The Italian Red Cross related that, during the malaria season, 80% of those having spent one night in the marsh became infected.[25]
Bonifica integrale
Starting in 1922, the Italian government's Department of Health, working with the Opera Nazionale Combattenti,[note 1] developed a new initiative to combat malaria called the bonifica integrale.[26][note 2] It featured three stages, the first being the bonifica idraulica, which would drain the swamp and control the waters. Mussolini and his party called it "the battle of the swamps" because it required the recruitment, deployment, and supply of an army of workers.[27] In the second stage, the bonifica agraria, homesteads with stone houses and public utilities were to be constructed and the land was to be parcelled among settlers. The third stage, bonifica igienica, took measures against the mosquitos (Anopheles labranchiae), such as screens and whitewash (so the mosquitos could be easily identified and killed), and against malaria, such as distributing quinine and setting up health services.[28]
In 1922 also,
Beginning in 1930, the bonifica idraulica cleared the scrub forest,[note 3] constructed a total of 16,500 km (10,300 mi) of checkerboard canals and trenches, dredged rivers, diked their banks, filled depressions, and constructed pumping stations to change the elevation in the canals where necessary. The final channel, the Mussolini Canal, empties into the Tyrrhenian Sea near Anzio. The project reached a peak in 1933 with 124,000 men employed. The previous agrarian population was moved out under protest in the name of progress. Workers were interned in camps surrounded by barbed wire. The camps were overcrowded, wages were low, hours were long, food was bad, sanitation was poor, healthcare was missing, and medical attention was lacking. Workers could quit, however, and turnover was high. In 1935, at the completion of the phase, they were all dismissed without notice. Many were infected with malaria.[29]
The government placed about 2,000 families (most from northern Italy) in standardised but carefully varied two-storey country houses of blue stucco with tiled roofs. Each settler family was assigned a farmhouse, an oven, a plough and other agricultural tools, a stable, some cows, and several hectares of land, depending on local soil fertility and the size of the family. Mussolini used the 10-year operation for propaganda purposes, and was often photographed between workers, shirtless with a shovel in his hand, or threshing wheat at harvest time; these occasions were regularly filmed by the Istituto Luce for inclusion in nationally shown propaganda newsreels.[30]
The new towns of Littoria (1932, now Latina), Sabaudia (1934), Pontinia (1935), Aprilia (1937), and Pomezia (1939) were founded, side by side with several other small borghi (rural villages). The carefully differentiated architecture and urban planning aspects of these towns is striking even today.[31][32]
Battle of Anzio
On September 8, 1943, Italy changed sides in World War II, the king having already issued an order for Mussolini's arrest. Rescued by the Germans, he became the head of the Republic of Salò, a puppet regime over northern Italy. The defense of Italy and the suppression of its insurgent population were left to the Wehrmacht. After the loss of Sicily, they successfully defended the Gustaf Line south of the marshes, necessitating an Allied landing at Anzio and Nettuno in an effort to outflank the Germans. Malaria had returned to the Agro Pontino: quinine and other medicines were in short supply or withheld by the Germans,[33] the food was bad, a shortage of metal prevented repair of the screens, and veterans returning from the Balkans brought back resistant strains of the disease.[34]
The Germans stopped the pumps and opened the dikes, refilling the marsh with brackish water. They were being advised by the German malariologists Erich Martini and Ernst Rodenwaldt that the return of the salt water would encourage the return of Anopheles labranchiae, which thrives in salty environments. The water would also destroy agriculture, removing essential supplies of food and fresh water from the vicinity, an act that had minimal military effect but devastated the population. Although it is true that the bog impeded movement of heavy equipment, the Germans did not flood the marsh for that reason; the equipment under heavy shelling from some of the largest artillery pieces the Germans had was going nowhere, anyway. The flooding was an act of biological warfare[33] and was opposed by former Italian colleagues of the Germans in malariology, but someone on Kesselring's staff - unknown to this day - issued the order.[34]
The allies and the Germans equally, therefore, found themselves fighting in a mosquito-infested bog. The new homes were being used as refuges for infantry and cover for tanks. Ernie Pyle relates:[35]
"On these little farms of the Pontine marshes Mussolini built hundreds of ... stone farmhouses ... Now and then I saw a farmer plowing while German shells landed right in his field. We tried to evacuate people ... But some of them simply refused to leave their homes. Sometimes the Germans would pick out one of the farmhouses, figuring we had a command post in it, I suppose, and blow it to smithereens. Then, and only then, did some Italian families move out ... on any side road we couldn't drive five minutes without seeing the skeleton of a cow or a horse."
Agro Pontino
The Battle of Anzio left the marsh in the state of devastation; nearly everything Mussolini had accomplished was reversed. The cities were in ruins, the houses blown up, the marshes full of brackish water, the channels filled in, the plain depopulated, the mosquitos flourishing, and malaria on the rise. The major structures for water control survived, and in a few years, the Agro Pontino was restored. In 1947, the province of Littoria, created by Mussolini, was renamed to Latina. The last of the malaria was conquered in the 1950s, with the aid of DDT.
Today, a duct system runs through the dried-out area. Wheat, fruit, and wine grapes are cultivated in the Pontine region. The "Agro Pontino" is a flowering landscape with modern cities with both prewar and postwar architecture. By 2000, about 520,000 inhabitants lived in this formerly deserted region. The Battle of the Swamps, however, is never quite over; without constant vigilance, dredging the canals, repairing and updating the pumps, and so on, the enemy would soon return. The specter of distant problems remains: the prospect of chemical pollution of the environment, DDT-resistant mosquitoes, and medicine-resistant strains of malaria.
