Successor to Odoacer, the Goth king Theodoric (493-526) ruled over Ravenna and contributed to the embellishment of the city. His mausoleum, built in 520, is a curious building, built from stones of enormous size and crowned with an astonishing monolithic dome 11m in diameter in Istrian stone. The very sober interior has a Romanesque porphyry basin converted into sarcophagus.
