Castello It is the largest and most populated district in Venice and it is certainly one of the most visited by tourists. It is a very suggestive area and you can’t leave the city without a stroll around its neighborhood. Situated on the eastern part of the city, it borders with the San Marco and Cannaregio districts and it is bounded from the lagoon of Venice. It is the only quarter not facing the Grand Canal. The Paglia Bridge (Ponte della Paglia) connects Castello with San Marco district and offers to the visitors a splendid view of the famous “Ponte dei Sospiri” (Bridge of Sighs). In the Castello district there is a lot to see: Carpaccio's paintings at the “Scuola di San Giorgio degli Schiavoni” are worth a long look and “San Francesco della Vigna”, with a Palladio facade and Sansovino interior, certainly deserves a stop. The churches of Santi Giovanni e Paolo, and San Zaccaria are major attractions and even the elegant “Riva degli schiavoni” promenade has plenty of interesting buildings: Palazzo delle Prigioni Nuove, Palazzo Dandolo, the Ponte della Ca ' di Dio, the Church of San Biagio and the Naval History Museum. Another milestone is the impressive Arsenal complex, remarkable for its historical value, and San Pietro island with the homonymous Church. The Castello district has beautiful public gardens housing some pavilions of the Venice Biennale International Art Exhibition.
