Huerto de Calixto y Melibea, Salamanca

You'll find this famous orchard in the old town, close to the Catedral Vieja (Old Cathedral) and the defensive walls. It's an oasis of lush vegetation and tranquility in the midst of the city and is probably the place that inspired Fernando de Rojas to write his novel La Celestina. All manner of plants and trees grow here: olive trees, cypress trees, acacias and almonds. Try and visit when they're in bloom. The two wells that the character "Melibea" fetched water from to water the sweet-smelling herbs are still here today, and so are the herbs - bay leaves, rosemary and mint. It's worth taking a walk through here to enjoy the garden and the views of the two cathedrals and the majestic Torre del Gallo tower. Admission is free.
