The Maiden Tower of Baku was built in the cylindrical form on the giant rock inclined towards the coast of the Caspian Sea. An oblong support (buttress) is attached to it from the seaside. The height of the tower on the northern part is 31 m, on the south- 28 m. The diameter of the tower on the first floor is 16.5 m. The thickness (width) of the wall on the first floor is up to 5 m. The interior part of the tower is divided into 8 floors. Each floor is covered with the arched ceiling made of cut stone. There are round holes in the middle of the stone ceilings. The holes are vertical. Thus when you look through the round holes in the middle of the 8 storey ceiling you can see the floor of the first storey. The single entrance to the tower is the arched doorway in its western part 2 m in height and 1.10 m in width. The height of the first floor of the tower is 3 m, the average height of the other floors is 2.5 m.
The inter-floor communication is maintained by means of stairs built within the southern –east wall of the tower. It is interesting that the communication between the first and the second floors can only be maintained through the round hole in the ceiling by means of a ladder or a rope. It should be noted that in past the door of the Tower was also multistage.
