The Romanesque style Elne Cathedral was consecrated in 1069. In 1285, during the Aragonese Crusade, French troops sacked the town and massacred the townspeople who had taken refuge in the cathedral.
Work began on rebuilding the cathedral in the 14th century but was never finished, which explains the irregular appearance of the main facade - the tower on the right was built at this time but not the tower on the left, so a much smaller tower was added later instead. The cathedral is notable for the lack of decorative stonework on the outside.
The cloisters were also built over the course of three hundred years, which explains why some parts are more ornamented than others - despite this the closters are very beautiful, with marble arches featuring interesting capital stones surrounding a nicely maintained garden. The cloisters now also contain a Museum of History and a Museum of Archaeology.
References:The Château Royal de Collioure is a massive French royal castle in the town of Collioure, a few kilometers north of the Spanish border. The Château is the juxtaposition of at least four castles. Roussillon was conquered by the Romans around 120 BC and then occupied by the Visigoths from 418. The first mention is about a fortified site in Collioure under siege in 673, by Wamba, king of the Visigoths who lay siege to the “Castellum Caucolibéri” to subdue a rebellion.
In the 12th century, Girard II, the last independent count of the Roussillon, bequeathed his land to Alfons II, King of Aragon and Count of Barcelona. Concerned about the prosperity of Collioure, the kings of Aragon granted privileges and tax exemptions. An annual fair was established, and important works were undertaken in the castle, the port and the town.
