Santa Marta, former church in Dorsoduro, Venice, Italy

Santa Marta is a deconsecrated church in Dorsoduro, near the port parking area, built of brick with a steeply pitched gable roof. Its plain facade holds only a small rectangular portal in a white stone frame; the right side, facing the car park, has a second stone-framed portal and a pointed-arch single window. Inside, a single nave with a wooden truss ceiling now contains a timber seating structure for conferences and exhibitions.

Founded in the early 14th century on the westernmost beach of the lagoon, Santa Marta grew from a hospice project of Giacomina Scorpioni, supported by Marco Sanudo and Filippo Salomone. The cornerstone was laid by Giovanni Zane, bishop of Caorle; in 1319 Scorpioni became abbess of a Benedictine convent. The church was rebuilt from 1446 to 1448, and the convent was later suppressed and the church deconsecrated.

The name comes from Saint Martha, to whom the monastery founded in 1319 was dedicated alongside the Apostle Andrew; it was soon called simply Santa Marta. Each year on the saint's feast day the abbess gave the Salamon family a silk rose, a symbolic tribute for their patronage. The church is now deconsecrated and used for conferences and exhibitions.

The church stands by the car park of the port area at the western end of Dorsoduro, near where the Canale Scomenzera meets the Canale della Giudecca. This is one of the few parts of Venice reachable by car, so it can be approached on foot from Piazzale Roma. The right side, facing the car park, has the second portal and the pointed single-light window.

The church was deconsecrated and used as a warehouse before a full restoration in the 2000s turned it into a venue for conferences and exhibitions. Inside, a wooden structure with seating now fills the centre of the single nave, whose ceiling keeps its wooden trusses.
