The old chapter house (built between 1356 and 1369 and known today as the Holy Grail Chapel) was originally where the canons met to discuss internal affairs. Today, it houses one of the most spectacular star vaults in Valencia.
In 1496, when the nave was extended to link the Bell Tower and the Chapter House, the architect Pere Compte built the connecting corridor. Compte, who was employed by the House of Borgia, also designed La Lonja in Valencia and the Monastery of Sant Jeroni de Cotalba in Alfauir near Gandia, where he created a magnificent Gothic spiral staircase, intricate sculptures, and the coffered ceilings of the upper cloister.
