Convento de Santa Marta

Convento de Santa Marta is a working 15th-century convent where Hieronymite nuns have been baking traditional sweets for over 500 years. You'll buy their dulces conventuales through a wooden revolving window called a torno, which keeps the cloistered sisters invisible while they sell you their handmade treats. The pastries include pestiños (honey-soaked spirals), roscos (anise cookies), and seasonal specialties like torrijas during Easter.

The experience feels like stepping back centuries. You ring a small bell at the wooden door, wait in a tiny stone vestibule, then speak to an invisible nun through the torno. She'll tell you what's available that day (always in Spanish), you place your money in the wooden compartment, and it rotates back with your sweets in simple paper bags. The whole interaction takes maybe five minutes, but the atmosphere is genuinely otherworldly.

Most guidebooks make this sound more mystical than it actually is. The sweets are good but not extraordinary, and you're essentially paying premium prices (expect 8-12 EUR for a small bag) for the novelty experience. Go if you're curious about monastic life, but don't expect gourmet pastries. The nuns often run out of popular items by afternoon, and they close unpredictably for religious observances.
