Carmen de los Mártires

This elegant and luxurious 19th-century mansion stands on a site with some gruesome history. During the Moorish occupation of the city, those who worked on building the Alhambra palaces and who knew too many royal secrets were imprisoned in dungeons here. During the 16th century, when Christians had conquered Granada, it became a convent. Later, in the 19th century, it was converted into a residential palace, which you can visit along with the wonderful gardens. It's located on the Alhambra hill, close to Manuel de Falla's House and Museum, above the Realejo district. Admission is free.
