The patron of Lagosanto is Saint Venantius, celebrated on 18 May.
The first weekend of August, usually from Friday to Tuesday, brings the Antica Fiera d'Agosto, a centuries-old tradition that reached its 449th edition in 2023: Friday evening's official opening is marked by a concert, while Saturday is dedicated to music with performances by local music schools. The town also holds the Church of San Giacomo and the «Orme nelle Radici» Sculpture Park.
