"My tomb on the bank of the Tiber"

The Mausoleum of Hadrian, more often referred to as the Castel Sant' Angelo, is a cylindrical stone building on the right bank of the River Tiber, built between 130 and 139 AD. Hadrian's ashes were deposited there, as were those of his wife, Vibia Sabina, and his first adopted son, Lucius Aelius. It was converted into a military fortress in 401 AD, and served as a papal castle in the 14th-16th Centuries.
