The Northern Bastion (Troia VI)
The Northeast Tower, the most massive of Troia’s bastions, belongs to the heavily fortified citadel of Troia VI. The tower encloses a ten-metre deep artesian well which was sunk during Troia VI and restored during Troia VII. This tower, which was also accessible from the outside, consisted of an enormous stone substructure measuring 18 x 8 metres and standing at least 9 metres high (today only seven metres). On top was a superstructure on unbaked mudbrick, although what this looked like is not known.

During the period of Troia VIII-IX the tower was built over by the enclosure-wall of the Athena temple precinct. During Troia VIII a narrow staircase, not visible from here, ran down the north face of the tower to another, more low-lying well. To the east the tower was joined by the circuit-wall of the lower town.
