The Agricultural Cooperative, also known as the Agricultural Union, is an academy-style building located at Ample Street, 17, in the town centre of Arenys de Mar, in the Maresme region.
This building was designed and built by Cèsar Martinell in 1947. The Agricultural Cooperative consists of a ground floor, a first floor and a roof.
On the ground floor we can see a large entrance door, with a lowered arch, flanked by two smaller doors. On the first floor, we can see three windows with straight gutters. This building ends with a railing, from the roof, with openwork stone.
