Ca la Pruna is an old fortified farmhouse located in the southern part of the municipality of Pals. It dates from the XV-XVI century and was, originally, a big home located outside the walls, which is why it is fortified. It consists of a ground floor and two floors. At the two ends of the main facade there are two defensive towers. The façade has a voussoir door and an upper gallery on the second floor. Currently it is the House of Culture where there is a small collection of field tools, measures and weights, and cultural activities, fixed and temporary exhibitions are carried out.
