The Venetian Island is composed of two parts: RIALTO (6 letters) and Isola (5 letters). RIALTO is the main island of Venice, located in the northern part of the Venetian Lagoon. It is home to many of the city's most famous landmarks, including the RIALTO Bridge and the Grand Canal. Isola is a smaller island located just south of RIALTO. It is known for its picturesque canals and colorful buildings. Together, these two islands form the heart of Venice and are a popular destination for tourists.
