Inverted Tower is one of the most visited tourist attractions of Portugal. It is situated in Sintra, Portugal. The tower is named as Inverted Tower because of the extraordinary construction of rooms branching off from an octagonal cave. The tower is an underground channel with a spiral staircase, which is supported by carved columns. The Inverted Tower has got a unique architectural design. It is one of the main attractions of Quinta da Regaleira, Sintra.
The nine hole round landings of the tower are separated by 15 steps that represent the 9 circles of paradise, purgatory or hell. The tower is connected to a cave that leads to a weird garden bounded by a lake. When we have a look at the tower, it appears as if the tower has sunk deeply into the earth. In spite of the fall of House Morcane in the year 1372 DR and the turn down of drow in the region after the Silence of Lolth, the insular community of Inverted Tower remained unaffected by the turmoil.
The tower is located in Quinta da Regaleira region in Sintra. This region belonged to a family of rich merchants from Porto named Barons of Regaleira. Carvalho Monteiro purchased the land in the year 1892. He wanted to build a mysterious place where he could showcase his interests and ideologies. With the help of an Italian architect named Luigi Manini, Monteiro built the 4-hectare estate with mysterious buildings that hides symbols related to Masonry, the Rosicrucians, alchemy and Manueline architectural styles. The design of the entire estate resembles the architectural style of Gothic, Renaissance, Roman and Manueline.
