The Basilica di San Francesco in Assisi is 2 churches stacked on top of each other on a hillside. The Upper Church (1228-53): soaring Gothic nave with Giotto's 28-scene fresco cycle of the Life of St. Francis (1296-1304) — the most important narrative painting cycle of the Middle Ages, the series that established Giotto as the father of Western painting. The Lower Church: darker, older, more mystical — with frescoes by Cimabue, Simone Martini, Pietro Lorenzetti, and the crypt containing St. Francis's tomb (discovered in 1818 after being hidden for centuries to prevent relic theft). Free entry. UNESCO. The spiritual epicenter of Franciscan Christianity.
28 panels on the lower walls depict the Life of St. Francis chronologically — from his youth as a wealthy merchant's son, through his renunciation of worldly goods (stripping naked before his father in the piazza), to the stigmata, death, and canonization. Key panels: Francis Renouncing His Father (Panel 5): Francis stands naked, his father restrained by bystanders, the bishop covering Francis with his cloak. The first painting in Western art where you feel genuine psychological tension between characters. Preaching to the Birds (Panel 15): Francis in a landscape talking to birds — the most reproduced Giotto image. The Dream of the Palace (Panel 3): Francis asleep, a palace floating above — Giotto painting a DREAM, interior psychological space made visible. Above Giotto: Cimabue and the Isaac Master painted Old and New Testament scenes (upper registers) — badly deteriorated (1997 earthquake + centuries of damage) but visible.
Darker, lower ceiling, more intimate. Simone Martini — Chapel of San Martino: 10 scenes from St. Martin's life (1312-18) — the most elegant Sienese painting in Umbria, gold backgrounds, courtly figures, exquisite detail. Pietro Lorenzetti — The Deposition: Christ taken from the cross, intense grief, dramatic Sienese color. Cimabue — Madonna and Child with Angels and St. Francis: In the transept — Cimabue's most important surviving work outside Florence. The Crypt: Descend to Francis's tomb — a simple stone sarcophagus surrounded by his four earliest companions. Silent, austere, profoundly moving.
