The people from this town are called Riudomenc/riudomenca.
Riudoms was a Roman rural settlement (some archaeological remains and coins were discovered), that was depopulated when the Muslims dominated the region in the 8th century. Conquered by the Norman Robert d'Aguiló under the orders of the Catalan count, the lordship of Riudoms was granted to Arnau de Palomar on 24 January 1150. A castle was constructed and a town born at side.
Although it is widely accepted that he was born in Reus, this village is considered by some people the place of birth of the architect Antoni Gaudí i Cornet, designer of the Sagrada Família church in Barcelona and the most famous creator of the artistic movement of Modernisme.
