This third palace, in Gothic style, was started about 1340. The first section was on the side facing the lagoon. In 1424 Doge Francesco Foscari built the wing overlooking the Piazzetta. This new building was for the law-courts, with a ground floor arcade on the outside. The first floor had open loggias running along the facade. When the Porta della Carta was built in 1442, it made an internal courtyard.
