A flight of steps sweeps down to Spoleto's pretty pale-stone cathedral, originally built in the 11th century using huge blocks of salvaged stones from Roman buildings for its slender bell tower. A 17th-century remodelling saw a striking Renaissance porch added. The rainbow swirl of mosaic frescoes in the domed apse was executed by Filippo Lippi and his assistants.
Lippi died before completing the work and Lorenzo de Medici travelled to Spoleto from Florence and ordered Lippi's son, Filippino, to build a mausoleum for the artist. This now stands in the right transept of the cathedral.
