Walking down from Rialto Bridge, you will enter a Sotoportego de l'Erbaria part of Venice, also known as the sister of San Polo. Enjoy the real Italian espresso in one of many sweet cafeterias or enjoy in lunch with a view on Grans Canal. You can also visit gothic San Giacomo di Rialto church, famous for its large 15th-century clock above the entrance. Venetians believe this is the oldest church in the city, dating from the 5th century.
