Wood Tower

The Wood Tower is a mediaeval tower in Mainz, Germany, with the Iron Tower and the Alexander Tower one of three remaining towers from the city walls. Its current Gothic appearance dates to the early 15th century. It is so named because wood used to be piled next to it on the bank of the Rhine.Like the Iron Tower, the Wood Tower was used as a watchtower and gate-tower and later as a gaol. It was badly damaged in World War II and accurately reconstructed in 1961 for the two-thousandth anniversary of the city. It currently houses various organisations and clubs.
