Cuzco was once the magnificent mountain capital of the Incas - until the Spanish breezed in, erecting their churches and grand colonial buildings on top of the existing Inca foundations. Today, this city high in the Andes is a picturesque maze of cobbled streets and squares and the base for the trek to Machu Picchu. The 17th-century Hotel Monasterio was originally the San Antonio Abad seminary, home to a community of Jesuit monks. Now a luxury hotel, the building has retained much of the original layout and the rooms are decorated with 16th- and 17th-century Cuzquenian paintings and murals. The oxygen supplementation system in the rooms to counteract the effects of altitude sickness is a welcome modern addition.
