CARDEDEU
Province : Barcelona
Origin/meaning:
The arms were granted on April 4, 2001.
The arms are canting: they show a "card" (Catalan for "thistle"), and the royal arms of Catalonia-Aragon (four red pales on gold) because the king Jaume I conceded in 1272 the charter and several privileges to the town (e.g. the permission to have fairs and markets, the highroad from Barcelona to Girona passing through the town, etc.).
