1. Rialto Bridge, also known as Ponte di Rialto, is one of the most iconic landmarks in Venice. It was built in the 16th century to replace an earlier wooden bridge and was considered a great engineering feat of its time. The bridge spans the Grand Canal and is made up of two inclined ramps, with rows of shops on either side. It is adorned with ornate sculptures and has a central portico.

Some interesting facts about the Rialto Bridge include:

- It was the only bridge across the Grand Canal until the 19th century

- The design of the bridge was initially controversial, with many critics believing it was too grand and expensive

- The bridge has survived several fires and collapses over the centuries, and has been rebuilt or repaired each time

2. The Rialto Bridge is open to the public 24/7 and there is no admission fee. There is no phone number for the bridge itself, but the nearest Tourist Information Center can be reached at +39 041 529 8711.

3. It is easy to access the Rialto Bridge by vaporetto (water bus) on the Grand Canal. The closest vaporetto stops are Rialto Mercato and Rialto, both of which are a short walk from the bridge. There is no ticket required to access the bridge, but visitors should be aware of pickpockets in the crowded area.
