The castle stands on the very steep edge of a long hill. The steep natural slope that defends the castle to the east required no more defense than a medium parapet.

The castle enclosure adapts to the shape of an irregular trapezoid and is made up of materials such as masonry and mud. The south and west sides meet at the Torre del Homenaje.

The Keep is almost square in shape, stands on rocky ground, and reaches 20 meters high. On the part where the rock does not appear, the builders arranged a stone base. The rest of the tower is made of masonry in regular rows, while the corners are made of more regular ashlar, which alternates with brick cores at the top.

It is structured in four floors supported by strong wooden beams in which, when it became a palatial residence, large windows covered with arches were opened. The staircase was located in the enclosure of the north corner.

Its façade, of great packaging and harmonious proportions, is representative of its palatial use, already in the 16th century, it is made up of a semicircular arch molded with large cut-off voussoirs and a corbel in the key that rests on large pilasters. Above the arch stands a well-carved noble shield of the first Count of Villardompardo, lord of Torres and Portugal.
