Torre de Ca l'Alzina
The Torre de Ca l’Alzina in Montgat is a defence or watchtower that was part of the Ca n’Alzina farmhouse (14th century). The tower has an apse plan; on one side it is rectangular and on the other it is semi-circular, and consists of a ground floor and two storeys.
The stone corbels and holes of two machicolations are preserved, one above the original door and another on the roof. A simple gargoyle is also preserved for the roof drain. It has been declared a Cultural Asset of National Interest.
The tower is currently being restored. Once the works are completed, it will be open to the public and will become a museum that will explain the defensive needs of the Renaissance
