With 960 in habitants, Castelldans harbours the ruins of a castle that was strategic during the Christian conquest. Mare de Déu de l’Assumpció church, which boasts a neoclassical façade, preserves a 15th-century polychrome stone Virgin and Child, and at the entrance to the rectory you can see the coat-of-arms of the Carthusian monks, some of whose decorative features can still be found on the ancient Carrer dels Frares.

The Mare de Déu de Montserrat hermitage was built in 1954, and the Museum of Olive Oil and the Rural World is worth a visit as well.

Between Melons and Matxerrí there is an area of great natural and ornithological interest. The project ‘Castelldans, Extra-Virgin Land’ offers four tourist routes which help visitors discover the natural and cultural heritage of the town and its three hills.
