An attack by the Saracens in 891, who remained until the end of the 10th century, devastated the country around current Cannes. The insecurity of the Lérins islands forced the local monks to settle on the mainland, at the Suquet (today the old town). Construction of a castle in 1035 fortified the city by then known as Cannes.
The castle was damaged in end of the 16th century and partially demolished in the 18th century. In 1919, the municipality of Cannes acquired all the buildings in order to house its museum. Today the Musée de la Castre hosts 19th-century Riviera landscape art, musical instruments & ethnographical items in a medieval tower.
The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed. The oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
