A few meters from the Relais you will find the archaeological ruins of the ancient walls of Jesolo, recovered thanks to the campaigns carried out by the nearby Ca’Foscari University of Venice. The ruins allow you to imagine two religious buildings, which were brought to light thanks to the meticulous activity of young grad students: the 9th-century Cathedral of Santa Maria Assunta and the church dedicated to San Mauro. They are free to visit.
