Sant Grau d’Ardenya is a large, neo-romanesque church in Tossa de Mar, located near a hill and attached to a construction that looks like a farmhouse. It has two floors, with two roof surfaces sloping down to the sides and the enclosure is made up of a church, a central patio and terraced rooms on the north, south and west sides. Moreover, near this enclosure there are several hotel facilities from the 1950s and 1960s, in ruins, including the water tower, the pond and the Sant Grau d’Ardenya wayside cross made of Girona limestone.

The Sanctuary’s patron saint is Sant Grau d’Aurillac, Alvèrnia-França(9th – 10th century). According to legend, there used to be a small oratory on this site where the saint slept and it was Maria de Montpeller, mother of King Jaume I el Conqueridor who, in 1200 AD, brought some relics of the saint there. These supposed relics are kept in the parish church of Sant Vicenç de Tossa.

The sanctuary of Sant Grau is one of the most emblematic places in Tossa and its surroundings, and the annual gathering is held there on 13 October. It is traditional to go there in small groups to eat rice and lamb chops around the sanctuary. Afterwards there is a sardana dance, a live lamb is raffled, and 17th-century hymns (1696) are sung in honour of Sant Grau.
