In its original state, it comprised a set of double gates set further back from the line of the walls, so that a square court was created that, covered by the walls and four towers set in its corners, served as a killing ground against attackers.

Layout and description
The Dipylon was the "largest gate of the ancient world", with a surface of c. 1,800 square metres (19,000 sq ft).[6] Its extraordinary size points to its use not only as a city gate, but also its ceremonial significance and monumental role as the starting point of the Panathenaic procession.[17]
Themistoclean structure
The original, Themistoclean-era gate largely established the final shape of the structure and covered the same area as the Hellenistic structure, and was built of clay bricks on top of a pedestal of Poros limestone blocks.
Archaeological evidence shows traces of later repairs, possibly under Conon, when the pedestal was covered with flat limestone blocks.[18] Parts of the Themistoclean wall are preserved only between the northwestern and southwestern towers,[19] but the towers themselves preserved several Archaic-period funeral monuments that were used as spolia during their construction, and were recovered by archaeologists.[20] The existence of two gates in the wall already during the Themistoclean phase is confirmed by preserved cart grooves; the southern gate is also crossed by a broad canal, which went parallel to the southern wall and then turned south, probably joining the Eridanos river nearby.[20]
Hellenistic structure
The Hellenistic gate complex was an altogether more massive and elaborate affair, being built of large finely hewn ashlar blocks, comprising a breccia core and covered with fine Piraeus sandstone slabs.[21] Apart from the north-eastern landward tower, the cores of the others survive to some height even today; originally they were probably covered with a tiled roof.[21] The curtain wall connecting them, originally 9 metres (30 ft) high and 4 metres (13 ft) thick and crowned with crenelations, some of which survive on the southern wall.[21] Access to both the walls and the towers was through staircases, one of which survives behind the cityward southeastern tower.[21] The northern cityward gate is still visible, but the southern one has been destroyed through the construction of a modern canal. However, the remains of the gate frames show that the gates were rectangular, in contrast to the second set of gates added in the late Hellenistic period, which were surmounted by marble apses. The pedestal of the central pier of the later set was built of marble spolia; in front of it, facing outward from the city, is a square marble pedestal, which may have hosted an equestrian statue of a Roman emperor or general.[22]
Well house
Just after the cityward gate, on the eastern side, between the gate and the stairway leading up to the wall, are the remnants of a well house, which was supplied with fresh water through underground aqueducts. The present structure was probably erected during the gate's reconstruction in 307/4 BC, but likely also had a Themistoclean antecedent, of which two pipes and a few Ionic column bases survive.[23] The structure was rectangular, divided into an L-shaped basin with low walls into which water flowed, and a small entrance hall that was supported by three Ionic columns. The entrance was between the second and third column. The floor, which largely survives, was built of marble slabs from Hymettus.[24]
Proteichisma
The proteichisma (προτείχισμα, "fore-wall"), which includes a wall as well as a moat in front of it, was erected during the Peloponnesian War, most likely as part of the repairs to the walls following an earthquake in 420 BC. They were extensively rebuilt under Conon, and again under Demetrios Poliorketes in the late 4th century.[25] Traces of the proteichisma survive particularly intact in the Kerameikos area,[25] including remnants of 4th-century BC pitfall traps against siege engines, consisting of 2 metres (6.6 ft) high pithoi let into the ground.[26]
The proteichisma comprised an 8 metres (26 ft)–high wall, placed some 6 metres (20 ft) in front of the main wall. As the ground sloped heavily between the two walls, the space had to be filled in, thus creating a flat surface that served as a ring road, that in the 4th century ran around the entire circuit of the wall and was used to connect the various quarters of the city. Following the reconstruction of the walls in 307/4 BC, however, this ceased to be the case, as the proteichisma received a roofed chemin de ronde, blocking the road.[27] The late 4th-century BC proteichisma was built of fine ashlar breccia masonry.[25]
