Theodoric himself in 520 had his tomb built in the Mausoleum of Theodoric. Its structure, which is divided in two decagonal orders one above the other, is made completely of Istria stone. The roof is made from a single block of Istria stone of some 10 metres in diameter and weighing 300 tons. There is a niche that leads down to a room that was probably a chapel for funeral liturgies. Stairs lead to the upper floor where there is a circular porphyry tub in which it is supposed Theodoric was buried, his remains were removed during Byzantine rule.
