Towers: Historic

Thumbnail Image Image-GoddenF11 The Campanile (Leaning Tower)(AD 1174). Famous case of tower instability. 52 ft diameter circular tower, 151 ft 3 in. high to the base of the belfry, and constructed as six stories of pillared galleries. The tilt of the tower is approximately 14 ft. An interesting example for calculating base stress due to eccentric loading. (Pisa, Italy)
Thumbnail Image Image-GoddenF12 View of Pisa Cathedral through one of the mid-height galleries of the Campanile. Note the angle of tilt from the vertical lines of the cathedral, and the scale of the gallery from the figure on the left. The tower is now closed to visitors due to the danger of collapse. The Cathedral and Baptistry are shown in slides GoddenE10-E11. (Pisa, Italy)
