[1][2] Lilaia lies on the northern slopes of Mount Parnassus and close to the springs of the Boeotic Cephissus.
[1] The tower lies about 1 kilometre (0.62 mi) southeast of the modern settlement, at the site of the acropolis of ancient Lilaea.
[1][2] The tower is built on top of the well-preserved Classical-era city wall,[2] and its lower part is built entirely of reused spolia, whereas the upper parts are built with quarried stone and brick.
[2] Its entrance was above-ground at the level of the first floor, on the western wall.
[2] Its exception size makes it very likely that it was the centre of an estate or fief.
