The best example of Iberian funerary architecture is the Iberian Burial Chamber of Toya, discovered at the beginning of the 20th century by "El Pernazas” when he was doing farm work and studying with Juan Cabré. It dates back to the Iberian culture of the 5th century and early 4th century BC.

The architectural structure of the Iberian Burial Chamber of Toya has a quadrangular floorplan and its interior is divided into three longitudinal naves, the central one, to the west, having the only door into the building. The two side naves, unlike the central one, are both divided into two spaces; the first, an antechamber, connects in both cases with the central nave. The stone blocks in the building, perfectly cut, were placed without the help of cramp irons or mortar, i.e, they were laid dry. Lastly, the doorway is characterised by a series of large stones supported on the walls of the longitudinal rooms.

Three naves were carved into the walls of The Iberian Burial Chamber of Toya, with a forth in the south wall of the southern nave. A low continuous bench also runs around the stone walls and eaves at the height of the base of the eaves. The doors are generally rectangular openings but the two linking the three naves show a distinctive characteristic of the Iberian construction of this area, with the last ashlars curving to give the impression of a false pointed arch instead of ascending to a vertical lintel. The trosseau of the chamber, which was not excavated using systematic methods, although it has been restored in part, is characteristic of an Iberian prince and his family, and includes the wheels for a soldier's cart and magnificent Attica kraters (decorated ceramic containers) attributed to the Toya Painter.

In 1918 it was declared a Place of Cultural Interest.
