The Cavallino Lighthouse is called "Piave Vecchia" because it takes its name from the old course of the Piave River, which used to flow into the Adriatic Sea before being diverted to improve navigability and prevent flooding. Although today it stands at the mouth of the Sile River, the area retains the name "Piave Vecchia" in memory of the old river outlet.
Located at the mouth of the Sile River in Cavallino-Treporti, the lighthouse is an iconic historical structure dating back to 1846, when it was built by the Austrians for military purposes. Originally designed to ensure safe navigation and for defensive purposes, the lighthouse was destroyed during World War II by German forces. Its reconstruction, carried out between 1949 and 1951, was managed by the Civil Engineering Corps of Venice. Today, the lighthouse features a cylindrical structure with distinctive black and white stripes, reaching a height of 48 meters, making it a landmark visible up to 18 nautical miles away.
More than just a navigational aid, the lighthouse stands as a testament to the region’s complex history, shaped by war and reconstruction. The area surrounding the lighthouse hosts a building that serves as the headquarters for the Coast Guard, which oversees the waters of the region. Access to the lighthouse and its immediate surroundings is not permitted, as the area is classified as military. This restriction preserves the institutional importance of the site, which, though not accessible to the public, continues to play a crucial role in maritime safety in the lagoon and the Adriatic.
