Of the Castle's Doors all that is left is the entrance arch and a pillory.

This pillory has a base composer by two square and flat steps in which the first one is covered by the floor. The prismatic shaft fits directly on the superior step. The section is square, slightly chamfered on the inferior part narrowing towards the top. The finish is composed by a cube above which settles another parallelepiped with lower faces encircled by rectilinear frames with traces from spherical finishing.

This pillory has four square steps, one monolithic column with a square base and an octave shaft. In the capital it is possible to see a round frame decorated with vegan symbols. Above the capital there are pinnacles which are remarkable pieces decorated with vegan symbols.

Donjon of the castle of Estremoz, with 27 feet high, built of white marble. It is thought that it was a work that went through three reigns: d. Afonso IV, d. Pedro and d. Fernando and it was the latter who designated it "Tower of the three crowns", the name by which this tower is known.

It is believed that this castle was built before the establishment of the nation, during the reign of Alfonso IX of León. Later, King Dinis recovered much of that region, ordering restoration and expansion works on its fortresses. King Manuel I granted a new charter to the town, leading to further restoration works. Currently, two square towers remain, one of the entrance gates bearing the royal crown and the coat of arms of King Manuel. Nothing remains of the wall that surrounded the town.

Medieval castle dating from 1283. In the 15th century, the keep underwent some alterations and, in the 19th century, it was acquired by its current owners. The architecture is both civil and military, with Gothic and Manueline influences.
