Tower of the Winds
One can easily tell the depth of excavation that was done within the last few centuries with the Tower of the Winds. The ground and wall that had once come up till the upper half of the tower now rests only a few feet above the base. The rounded arches to the side of the tower also seems to have undergone some extensive restoration as the inner one is now filled with bricks and both supported by steel poles. The wall surrounding the Acropolis is shorter, with cranes in the background to help with restoration. The doors leading into the tower are gated, however, they are open to the public to view during open hours, and the buildings in the back are all new. However, the surrounding area of the tower seems to have been mostly finalized by the time Clement and Cie Braun took their photo between 1889 and 1909 as the sloped fences, blocked arch, and foliage have remained very similar.
