Camera Obscura

Access to guided tours of the Camera Obscura is restricted to participants and is included in the Castle ticket price.

Discover the city of Lisbon on a tour of our Periscope that allows us to examine the surrounding area in real-time.
The Periscope / Camera Obscura is an optical system of lenses and mirrors that allows visitors to observe the city in real time in great detail, including its monuments and most emblematic areas, the river, and the city of Lisbon, in a 360º view.
The equipment is installed in one of the most emblematic towers of Castelo de São Jorge. Now called Ulysses Tower, it once held some of the most important documents in the kingdom of Portugal, famously known as Torre do Tombo between the 14th and 17th centuries.
