Quinta Da Regaleira complex is spread over nearly 10 acres. The Palace of Regaleira is the main building of the Quinta Da Regaleira complex. While, the palace has five floors, visitors can only access the first floor. Despite this, there's a lot to see in the Quinta da Regaleira interior. You can explore the entire ground floor, which was the meeting area for the Monteiro family, and the first floor, which had the family's private rooms, bathrooms, and playrooms. Additionally, you can access the Hunting Room, Renaissance Room, Kings' Room, and Smoking Room.
