Porta San Giorgio stands in the Oltrarno at the junction of Via San Leonardo and Costa San Giorgio. It formed part of the city’s second defensive line.
Built around 1320, it was lowered in 1529 before the siege of Florence. Michelangelo ordered the alterations, working from Porta San Miniato as far as Porta San Giorgio.
Its name comes from the church near Costa San Giorgio.
The façade has a double arch and, outside, a fourteenth-century relief of St George killing the dragon. Inside is a fresco by Bicci di Lorenzo of the enthroned Madonna and Child with Saints Leonard and George.
