This strange cathedral was built in the 16C on the site of a former mosque. The frequent attacks by Berber pirates explain its fortress-like look, creneled towers and fortified walls. On the side, enter the main gate, a large 17C tower housing the bells and ending in a small wall. The fine Renaissance main portal contrasts with the austere façade but the rich décor does not alter the classic design. Just before entering, note the curious Portocarrero Sun - an animated sun, symbol of the town - sculpted on the chevet. Inside, the three Gothic naves of this church are topped by vaulted ceilings standing on identical columns. The capilla mayor, which has kept its Gothic vault, was rebuilt in the 18C (tabernacle, retable, arches). Note the Renaissance stalls in the coro, especially the strange medallions decorated with cameos on the upper stalls, and the sculptures of people in movement. The neo-classical trascoro, with its multi-coloured marble, is by Ventura de Rodríguez. In the transept, a flamboyant Gothic style door used to lead to the cloister. Three chapels are arranged around a walkway: the Gothic axial chapel contains the Christ of Hearing, particularly venerated in Almería; the lateral chapels are Renaissance. Saint Indalecio, patron saint of Almería, rests in the right-hand chapel and paintings by Alonso Cano decorate the chapel to the left.
