Leaving behind you the Scrigno Room, you will cross the Chamber of the Navy Captains to reach the museum bookshop. After leaving the bookshop, go down the stairs and pass through the museum café to reach the ground floor through a door that faces the back side of the Scala dei Giganti. Before passing through the tunnel-like corridor, you’ll encounter the Foscari Arch (no. 35 in the official audioguide).
