Even if you’ve already overdosed on colonial edifices, this convent shouldn’t be missed. Occupying a whole block and guarded by imposing high walls, it is one of the most fascinating religious buildings in Peru. Nor is it just a religious building – this 20,000-sq-meter complex is almost a citadel within the city. It is a disorienting place with twisting passageways, ascetic living quarters, period furnishings and religious art – a photographer’s paradise.
