The Arenyenc Athenaeum is a building located at Josep Anselm Clavé Street, 20-22, in the town centre of Arenys de Mar, in the Maresme region.
This Athenaeum was founded in 1884 by a group of people who frequented the cafe in Flos. At first, this Athenaeum met in the same Café, until, between 1888 and 1910, the building of the Arenyenc Athenaeum was built.
This building consists of a ground floor and three upper floors. The entire facade follows a symmetrical axis, with two openings on the ground floor, and the two upper floors, and four windows on the third floor.
What is most striking about this building is the sgraffito decoration that can be seen on the façade.
