Near to the castle is the church of San Remigio, built in the 13th century by the Bishops of Luni. The baroque church contains the marble tomb of the former Marquis Galeotto Malaspina. The Oratorio della Compagnia dei Bianchi (Oratory of the Fellowship of the Whites) was built in the 16th century and features a white marble facade donated by Pasquale Malaspina in 1666.[4]
Fosdinovo is the seat of the Medieval Festival of Fosdinovo (July) and the Forza del Sorriso Festival (Strength of the Smile Festival) (the fourth weekend of August). This second festival is a new, vital festival where the chief theme is the smile.
