Inside the Cathedral in Orvieto

The exterior walls of the church as well the six foot in diameter columns inside, alternate basalt and travertine layers, so are black and white all the way towards the sky.

Inside the Cathedral of the Assumption of Mary in Orvieto, the apse and two transcepts are each covered on the sides and ceilings in frescos from the 1300 and early 1400s, in the style of Giotto, when painters combined medieval narrative with modeling. Especially lovely was the fresco by Fabriano, near the entrance, done in 1325.
