Chiesa di S. Maria della Scala

The church of S. Maria della Scala is a Gothic essay in measured geometry and vertical lift. Its three naves are arranged with a mathematical clarity typical of the period: the central aisle is not quite double the width of the side aisles, and the square bays of the main vessel correspond to two almost-square bays in each side aisle. Every central bay carries a ribbed cross-vault, echoed by two more on either side. The main vaults rest on clustered piers, with slimmer circular columns inserted between them to support the pointed longitudinal arches and the transverse arches of the side aisles. A short transept, also vaulted, cuts across the three naves; small doors in its flanks open onto the piazza and the canonica’s garden. Beyond the transept, two further bays contain the raised presbytery and choir, the latter ending in a five-sided polygonal apse. The sanctuary floor is six steps higher than the nave, allowing space for the crypt’s vaults below. Two square-plan chapels flank the presbytery, and a square-based campanile rises beside the right-hand chapel.
