Tower of Can Cabirol Monument · Arenys de Mar, Maresme, Barcelona The Torre de Can Cabirol is an old rectangular defence tower located on a street of terraced houses in Arenys de Mar, in the Maresme (Barcelona), declared a Cultural Asset of National Interest. Only the upper part, with a turret on one of its sides, stands free; the rest forms part of a group of dwellings that has greatly altered its original appearance, with a ground floor now converted into three storeys with windows. Arenys de Mar, a town since 1599 and of great maritime importance in the 18th and 19th centuries, had to raise defence towers such as this one in the face of the danger of piracy on its coast.
