The site is located in the semi-rural area of the parish of Santa Maria do Castelo e São Miguel, along one of the flanks of the Serra do Varatojo mountain range.
Situated on a platform, the location extends down towards the Sizandro River, approximately 3 kilometres (1.9 mi) from the urban center of Torres Vedras.

Only the central part of the original fortification remains.
The interior courtyard includes a space approximately 25 metres (82 ft) diameter, circled by a solid wall, which runs independently for several metres.
The exterior is reinforced by 10 cubels with diameters varying between 6 metres (20 ft) and 7 metres (23 ft) in a semi-circular layout; four are complete, one is partly complete, and the remaining five are completely destroyed.
The walls themselves range from 1.6 metres (5.2 ft) to 3.6 metres (12 ft) in width and 3 metres (9.8 ft) to 7 metres (23 ft) in height.

There are four doors within the structure (south, north, northeast and west), with the likelihood that six doors or passageways provided access to the courtyard between the fortifications inner and outer walls.
These passages were short and narrow and permitted only one person at a time from accessing the spaces, likely on all-fours.
One of the spaces connects the battlement's gallery and these passages.

The houses on-site were oval shaped, approximately 6 metres (20 ft) in diameter, and made from adobe.
