Barcelona, the traditional centre of Catalan movements for independence, is the capital of both the province of Barcelona and the autonomous community of Catalonia. The city is governed as a municipio (municipality) of Spain, and its elections are held every four years.
Sabadell, city, Barcelona provincia (province), in the comunidad autÃ³noma (autonomous community) of Catalonia, northeastern Spain. The city, just north of Barcelona, originated as an Iberian and Roman settlement known as Arragona and became a medieval fief of the Castle of Arahona. Called Sabadell in the 12th century, in 1373 it was incorporated as a royal village (with municipal rights) in the kingdom of Aragon. Sabadellâs architecture is essentially modern; most of its older churches and buildings were destroyed during riots in 1835 and 1909.
