A visitor taking pictures inside the Castle of Sammezzano in Leccio, Florence, in Italy's Tuscany region, during a special opening to the public on Sunday.
The palazzo, first built in 1605 by Spanish nobleman Ferdinando Panciatichi Ximenes of Aragon, has 365 rooms decorated in Moorish Revival architectural style.
It was looted during World War II and later turned into a hotel, before being shuttered and abandoned in the 1990s.
The palazzo fell into disrepair over the years, prompting the community to petition the local government to "take all actions aimed at its protection, conservation and development as part of our cultural heritage".
The castle, which sits on 185ha in the Florentine countryside, will go under the hammer in February with an expected price tag of £10.6 million (S$22.4 million).
