Planetário de Marinha, Naval planetarium in Belém, Portugal
The Planetário de Marinha is a naval observatory in Belém featuring a central dome where 32 projectors create an immersive sky display. The system renders roughly 9,000 stars and various astronomical phenomena visible from both hemispheres.
The facility opened in 1965 and was built next to the Maritime Museum and Jerónimos Monastery. It quickly became a center for astronomical education in the region.
The facility presents astronomical programs in multiple languages and demonstrates how sailors once used the stars to find their way across oceans. This connection between sky and sea remains at the heart of what the place teaches.
The facility offers regular public shows at set times throughout the week. Visitors should check the schedule in advance and allow time to explore the grounds at a leisurely pace.
Within the complex sits the Commander Conceição Silva Observatory, which allows visitors to conduct personal astronomical observations. This extra facility transforms the place into more than a simple viewing venue.
