Quinta da Regaleira is an estate located near the historic center of Sintra, Portugal
. It's 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 Pena, Monserrate and Seteais palaces), it's 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 palace is also known as "The Palace of Monteiro the Millionaire", which is based on the nickname of its best known former owner, António Augusto Carvalho Monteiro.
The Regaleira Palace (Portuguese: Palácio da Regaleira) bears the same name as the entire estate. The structure's façade is characterized by exuberantly Gothic pinnacles, gargoyles, capitals, and an impressive octagonal tower.
The palace contains five floors (a ground floor, three upper floors, and a basement). 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.
The Regaleira Chapel is a Roman Catholic Chapel, and stands in front of the palace's main façade. Its architecture is akin to the palace's. The interior of the chapel is richly decorated with frescoes, stained glass windows and lavish stuccoes. The frescoes contain representations of Teresa of Ávila and Saint Anthony, as well as other religious depictions. Meanwhile, the floor itself offers depictions of the armillary sphere of the Portuguese discoveries and the Order of Christ Cross, surrounded by pentagrams. Despite its relatively small size, the chapel has several floors.
Much of the four hectares of land in the surrounding estate consists of a densely treed park lined with myriad roads and footpaths. The woods are neatly arranged in the lower parts of the estate, but are left wild and disorganized in the upper parts, reflecting Carvalho Monteiro's belief in primitivism. Decorative, symbolic, and lively structures can be found throughout the park.
The park also contains an extensive and enigmatic system of tunnels, which have multiple entry points that include: grottoes, the chapel, Waterfall Lake, and "Leda's Cave," which lies beneath the Regaleira Tower. The "Initiation Well" (see next section) connects to other tunnels via a series of underground walkways.
The Initiation Wells (AKA initiatic wells or inverted towers) are two wells on the property that better resemble underground towers lined with stairs. These wells never served as water sources. Instead, they were used for ceremonial purposes that included Tarot initiation rites. The tunnels described above connect these wells to one another, in addition to various caves and other monuments located around the park. Of the two wells, the larger one contains a 27-meter spiral staircase with several small landings.
Lakes, Fountains and the Aquarium:
Bodies of water can be found in several places in the park. Two artificial lakes and several fountains were added by Monteiro. One of the most interesting and extravagant among them is the Aquarium, built as if it were naturally embedded in a large boulder. It was once considered the most important naturalist property in Regaleira. However, the Aquarium is no longer used and is poorly maintained.
