This square tower made with thick granite blocks (reaching two metres) was founded in the XV century by the 8th Count of Barcelos. The finishing is from the Renaissance period with cornice, gutter and merlons.

There are still, in some points of the historic centre, remains of the Primitive Wall, which remounts to the year 400. This wall had four doors or entrances. The main door was the Vandoma Arch that was east of the borough, between the Largo da Sé and the Rua Chã. From here, the wall surrounded the hill following closely the Escadas das Verdades (stairs), where the Mentiras Arch or Door used to be.

From the former defensive walls in Santarém that in other times possessed fourteen doors and hatch, today it only remains some vestiges in some parts of the city. It can be observed next to the Sol (Sun) door with three small towers, on the proximity of Traição (Betrayal) door and several other things spread through the city. From the former doors the one who still exist are Santiago, Sun, Leiria and the Palace (Paço) which are a small sample from what the town used to be.

Door in the village fence, to present a full arc with barrel vault.

This is one of the ancient city gates, in stone and Gothic style.
