9 August marks the anniversary of the laying of the foundations of the tower known to all as the Leaning Tower of Pisa. Construction of the first floor began in 1173 and had progressed to the third floor in 1178 when the tower began sinking.

Building began again in 1272, by which time the tower had settled firmly, but the new floors were tilted to take into account the lean of the lower floors, which caused the tower to begin leaning the other way.

Construction stopped again in 1284, was resumed in 1319 and the bell tower at the top finally completed in 1372. Efforts to preserve the tower have involved removing soil from under the ‘high’ end to reduce the tilt, which is now around 4 degrees.
