The Antxia Tower is located in the historic quarter of Markina-Xemein. It is a construction with an approximately quadrangular ground plan and a parallelepiped volume, with overhanging wooden eaves and a hipped roof. Its main facade has an irregular layout and is structured in several levels: ground floor, first floor, second floor and attic.
On the ground floor, there are two entrances: one with a bell-shaped arch and the other with a semicircular arch with voussoir, made with quality ashlars. On the first floor there are four pointed windows with mullions, two of them with decoration on their threads. At one end of the floor, and at a lower level, there is another lintelled opening.
On the first floor, around a central segmental opening, there are twinned segmental openings leading to a balcony supported on corbels. It is a modern wrought-iron balcony, but its construction took into account the lines of the building, so it is in keeping with the aesthetics of the tower. A new row of corbels leads to the attic, which has four lintelled openings.
The main façade has a solid ashlar masonry structure that culminates at the height of the attic, a register made of modern timber framing. The rear façade is made of masonry, except for the edges and the window surrounds (arrow slits and two pointed openings), which are made of ashlar. The side façades are also made of masonry and are currently covered with rendering.
Antxia is a good example of the towers that were built in Bizkaia in the late medieval period.
In the Markina bonfire of 1630, it is listed as belonging to Doña María de Ugarte. It is a well-carved ashlar tower with twin Gothic windows and pointed doors. It has three floors and an attic.
