The Renaissance Palazzo della Corgna was designed by the Perugian architect Galeazzo Alessi. In 1550, Giulio III del Monte’s nephew Ascanio della Corgna became governor, and because of the presence of Della Corgna’s family, artists came to the town to construct and decoration the new palace. The interior has some good 16th Century frescoes by Pomarancio and Salvio Savini and on the ground floor is a small 6th Century BC sandstone obelisk, brought here from the convent of San Francesco. Close to the palace is what locals claim is the narrowest lane in Italy.
