Basilique-Cathédrale de Saint-Jean-Baptiste de Perpignan
Work on this large brick cathedral began in 1324 during the rule of King Sancho I of Majorca. The fall of the kingdom and the Black Death impeded works, and the building was only finished in 1509. It became a cathedral in 1602. It's been modified many times over the centuries and the oldest part is the choir with its seven-sided apse. Attractions include the white marble main altarpiece with scenes from the lives of Jesus and St John the Baptist, and altarpieces of Notre-Dame-de-la-Magrana and Saint-Pierre. There's also a small chapel with sacred art of the early 14th century, and a wooden crucifix brought here from the Rhine Valley. The western façade of the cathedral has a bell tower with a bell made in 1418.
The "field of saints" is a cemetery built from 1300 and used until the French Revolution. It's a brick cloister, with wealthy people buried in its arcades and the less well-off in the middle - now a grass field, formerly an ossuary. The oldest visible grave dates from 1317. It's occasionally an event space.
This Dominican monastery was created in 1245, housing some 60 monks, and remained active until the Revolution. It has a large 18th century chapel, a chapter house, cloister, refectory and dormitories. The only part you can see is the chapel, used as an art exhibition space. The rest of the complex is military, organising French national service.

This was the medieval stock exchange and commercial chambers. It's now the Tourist Office.
Bernat Xanxo was a wealthy draper and had this mansion built in Catalan Gothic style in 1506. It's now a small art museum, but the building itself is the main attraction, with the ceremonial living room, and the frieze with symbols of the cardinal sins and the flames of hell awaiting.
