Christian Site in Siena

Remarkably, this vaulted space under the Duomo's pulpit was totally filled with debris in the late 1300s and was only excavated and restored in 1999. Originally functioning as a cathedral entrance and confessional, it was decorated with 180 sq metres of richly coloured 13th-century pintura a secco ('dry' or mural paintings) covering walls, columns, pilasters, capitals and corbels. Fortunately, these managed to survive their ignominious treatment.
