The cathedral was built in the CatalanGothic style, because of its association with the Kingdom of Majorca. It has a wide nave (80 meters long, 18 m wide, and 26 m tall) made of seven cross-vaults, and features a short transept and apse, whose vault features seven keys.
The cathedral's western façade was never finished. When being restored in the 19th and 20th centuries, the Gothic window of the façade was rebuilt, as it had previously been substituted by a simple rectangular opening. The façade also features a portico and clock-tower, which date from the 18th century.
