Fodor's Expert Review Basilica di San Francesco
The basilica isn't one church but two: the Gothic church on the upper level, and the Romanesque church on the lower level. Work on this two-tiered monolith was begun in 1228. Both churches are magnificently decorated artistic treasure houses, covered floor to ceiling with some of Europe's finest frescoes: the Lower Basilica is dim and full of candlelight shadows, while the Upper Basilica is bright and airy.
In the Upper Church, the magnificent frescoes from 13th-century Italian painter Giotto, painted when he was only in his twenties, show that he was a pivotal artist in the development of Western painting. He broke away from the stiff, unnatural styles of earlier generations to move toward realism and three-dimensionality. The Lower Church features frescoes by celebrated Sienese painters Simone Martini and Pietro Lorenzetti, as well as by Giotto (or his assistants). The basilica's dress code is strictly enforced—no bare shoulders or bare knees are permitted.
