The 16th-century monks of Évora knew life was short. As if to ram home the point, they decorated an entire chapel with bones dug up from the town’s overflowing cemeteries. The sign outside the Chapel of Bones roughly translates as “We bones in here wait for yours to join us”. Cheerful lot, those monks. Columns, walls, arches – all are covered in skulls, tibias, fibulas, clavicles. Rapt, I can’t stop staring, then start to chuckle when I see skulls curving round frilly frescoes of cherubim on vaulted ceilings, a whimsical touch of chintz among the ghoulishness.
