Trajan's Bridge (
The bridge was constructed in 105 AD by Emperor
The Site
The bridge was situated east of the
.Construction of the bridge was part of a wider project, which included the digging of side canals so that
The remains of the embankment which protected the area during the construction of the canal show the magnitude of the works. The 3.2 km (2.0 mi) long canal bypassed the problematic section of the river in an arch-like style.[4] Former canals were filled with sand, and empty shells are regularly found in the ground.[5]
All these works, especially the bridge, served the purpose of preparing for the
The bridge was 1,135 m (3,724 ft) long (the Danube is now 800 m (2,600 ft) wide in that area), 15 m (49 ft) wide, and 19 m (62 ft) high, measured from the surface of the river. At each end was a Roman fort so that crossing the bridge was only possible through the camps.
On the south bank, at the modern village of
On the north bank is the Drobeta fort. It also had a bronze statue of Trajan.[5]
Design and construction
Apollodorus used wooden arches, each spanning 38 m (125 ft), set on twenty masonry pillars made of bricks, mortar, and pozzolana cement.[6][7] It was built unusually quickly (between 103 and 105), employing the construction of a wooden caisson for each pier.[8]
Apollodorus applied the technique of river flow relocation, using the principles set by
The bricks also have a historical value, as the members of the

Relocation
When the plan for the future hydro plant and its reservoir was made in 1965, it was clear that numerous settlements along the banks would be flooded in both Yugoslavia and Romania, and that historical remains, including the plaque, would also be affected. Serbian Academy of Sciences and Arts urged for the plaque to be preserved and the government accepted the motion. The enterprise entrusted with the task of relocation was the mining company "Venčac" as its experts previously participated in the relocation of the Abu Simbel temple in Egypt.[9]
First idea was to leave the plaque at its position and to build the
In the end it was decided to dig in a new bed into the rock 22 m (72 ft) above the plaque's original location. The plaque was then cut in one piece with the parts of the surrounding rock and road. After being cut with the cable saws, the 350 tons heavy chunk was lifted to the new bed. Works began in September 1967 and were finished in 1969.[9]
Destruction and remains
The wooden superstructure of the bridge was dismantled by Trajan's successor, Hadrian, presumably in order to protect the empire from barbarian invasions from the north.[10] The superstructure was destroyed by fire.[5]
The remains of the bridge reappeared in 1858 when the level of the Danube hit a record low due to the extensive drought.[5] The twenty pillars were still visible.
In 1906, the Commission of the Danube decided to destroy two of the pillars that were obstructing navigation.
In 1932, there were 16 pillars remaining underwater, but in 1982 only 12 were mapped by archaeologists; the other four had probably been swept away by water. Only the entrance pillars are now visible on either bank of the Danube,[11] one in Romania and one in Serbia.[5]
In 1979, Trajan's Bridge was added to the Monument of Culture of Exceptional Importance, and in 1983 on
