The castle consists of two enclosures. The external one is polygonal and reinforces the fortification on the hill's gentler slopes. At the southeast, on the top of the hill, rises the interior enclosure, hexagonal in shape, which consists of a row of vaulted chambers set around a large central court.

The walls of the exterior enclosure feature a chemin de ronde (a walkway for soldiers) and battlements. Their present form, as well as the three towers on their western part, dates to the Ottoman period.

The central entrance is located on the northwestern side of the external enclosure and initially consisted of a gate. This initial Frankish structure had a single entrance, a simple walkway that ended at the gate. Its current form consists of two additional consecutive gates, in front of the Frankish one, and a rectangular vaulted space; these modifications belong to the Ottoman period.

Along the walls' periphery, architectural remains of the initial 13th-century Frankish structure are preserved, as are the cisterns and traces of the outer enclosure's pipelines.

Traces of structures preserved in various places in the outer enclosure may date to Ottoman times. Amongst them, stand the remains of a Turkish mosque.

The inner enclosure is uniform and dates to the Frankish period, with no later modifications to its architectural details.

The entrance is on the northwestern side of the hexagonal building and consists of two consecutive gates and a passage. East of the gate on the upper floor, the remains of the castle's chapel are preserved. The inner enclosure consists of a row of consecutive vaulted halls that enclose the central court. The halls are enclosed by chambers that served as walkways for the military and were accessible from the inner court via a built staircase.

Inside the inner enclosure were the castellan's or the prince's residence, along with reception halls, kitchen, and billets for the guards. The halls were two-storeyed (except for hall G). Inside them, cisterns are preserved, as well as numerous fireplaces similar to those found in the buildings of the external enclosure, storage niches, and latrines. Access to the halls was provided through the inner courtyard; those on the upper floor were approached by external built stairs. They were corbelled with semi-elliptical vaults, which, combined with the wall openings with domes and the slightly pointed arches of the wall openings, confirm the western origin of the castle's founders.
