The garden is built atop the site of the former Royal Palace of the Portuguese monarchs.
The name 'Portas do Sol' translates to 'Gates of the Sun', referring to the ancient eastern defensive gate of the medieval castle.
The site contains the ruins of the Torre das Cabaças, a 15th-century tower originally part of the city walls.
Archaeological excavations at the site have uncovered structural foundations dating back to the Islamic occupation of Santarém.
The garden is one of the few places in the region that provides a direct, elevated vantage point to observe the annual flooding patterns of the Tagus River plains.
Jardim Portas do Sol is a landscaped garden situated within the walls of the ancient castle of Santarém. It occupies the highest point of the city, offering an expansive panoramic view over the Lezíria Ribatejana and the Tagus River valley. The site occupies the footprint of the former Alcáçova, the Moorish fortress that once stood here. The garden grounds contain remnants of medieval stone fortifications and archways integrated into the landscape. It serves as a public leisure space featuring well-manicured hedges, flower beds, and shaded benches. The location represents the strategic defensive position of the city during the Reconquista. A small playground and a designated rest area provide amenities for visitors.
