The Regalera estate has the Regalera Palace, the Regalera chapel, and a luxurious park with lakes, caves, wells, benches, fountains and a wide variety of beautiful buildings. The most famous is a 27-meter-deep Sakai, surrounded by spiral staircases, with nine spiral floors, symbolizing the nine cycles of heaven, hell and purgatory described by Dante. If you have enough time, you can also enjoy the buskers' music performance in the open air space.
