Quinta da Regaleira is a quinta located near the historic center of Sintra, Portugal. It is classified as a World Heritage Site by UNESCO within the "Cultural Landscape of Sintra". Along with the other palaces in the area such as the Quinta do Relógio, Pena, Monserrate and Seteais palaces, it is considered one of the principal tourist attractions of Sintra. The property consists of a Romantic palace and chapel, and a luxurious park that features lakes, grottoes, wells, benches, fountains, and a vast array of exquisite constructions.

The ground floor consists of a series of hallways that all connect the living room, dining room, billiards room, balcony, some smaller rooms, and several stairways. In turn, the first upper floor contains bedrooms and a dressing room. The second upper floor contains Carvalho Monteiro's office, and the bedrooms of female servants. The third upper floor contains the ironing room and a smaller room with access to a terrace. Finally, the basement contains the male servants' bedrooms, the kitchen (which featured an elevator for lifting food to the ground floor), and storage rooms.
