Here are a few popular sites in Venice.

Piazza San Marco, often known in English as St Mark’s Square, is the principal square of Venice. The Piazza is dominated by the Basilica, the Doge’s Palace and the Basilica’s campanile, which stands apart from it.

The Rialto Bridge is a bridge spanning the Grand Canal in Venice, Italy. It is the oldest bridge across the canal and probably the most famous in the city.

The Bridge of Sighs is one of many bridges in Venice built in the 16th century. The enclosed bridge is made of white limestone and has windows with stone bars. It passes over the Rio di Palazzo and connects the old prisons to the interrogation rooms in the Doge’s Palace.

The view from the Bridge of Sighs was the last view of Venice that convicts saw before their imprisonment. The bridge name, given by Lord Byron in the 19th century, comes from the suggestion that prisoners would sigh at their final view of beautiful Venice out the window before being taken down to their cells.

Here are some popular sites in Florence, Italy.

The Basilica di Santa Maria del Fiore is the cathedral church (Duomo) of the Roman Catholic Archdiocese of Florence, noted for its distinctive dome.

The Ponte Vecchio is a famous medieval bridge over the Arno, in Florence, Italy, noted for having shops (mainly jewelers) built along it. It is Europe’s oldest segmental arch bridge.

The Palazzo Pitti is a vast mainly Renaissance palace in Florence, Italy. In the 19th century, the palazzo, by then a great treasure house, was used as a power base by Napoleon, and later served for a brief period as the principal royal palace of the newly-united Italy. In the early 20th century, the palazzo together with its contents was given to the Italian people by King Victor Emmanuel III; subsequently its doors were opened to the public as one of Florence’s largest art galleries. Today, housing several minor additions in addition to those of the Medici family, it is fully open to the public.
