The tholos of El Romeral, also known as dolmen of El Romeral or cave of El Romeral, is a megalithic monument that was declared a World Heritage Site on July 15, 2016 and recognized as an Asset of Cultural Interest. This monument is located in the second enclosure, less than two kilometers from the dolmens of Menga and Viera, located on the axis that connects the Menga dolmen with the Peña de los Enamorados.

The structure of El Romeral stands out for its typology of dome formed by the approximation of rows, typical of the Mediterranean tradition, and for its unusual double orientation: on the one hand, towards the mountain range of El Torcal, which underlines its geographical link, and on the other hand, towards the solar ortos during the noon of the winter solstice, showing an astronomical interest. It is constituted by a linteled corridor of trapezoidal section that extends for four meters, built with big flagstones and small stones. At the end of the corridor there are two circular chambers, being the first one of greater diameter and destined to the offerings, which includes an altar stone. These chambers are erected by means of small protruding stones in each course compared to the lower one, which allows to obtain a vaulted section; at the end, the system is closed with a cover. The whole complex is protected by a mound of 75 meters in diameter, surrounded by a perimeter of cypress trees.

The history of the tholos goes back approximately to the period between 3000 and 2200 B.C. during the Chalcolithic period. It was discovered in August 1904 by the brothers José Viera Fuentes and Antonio Viera Fuentes, officials of the Antequera Town Hall, who initially called it Sepulcro del Cerrillo Blanco. Later, the architect Ricardo Velázquez Bosco established the name of El Romeral, referring to the property where it was found, owned by the Antequera politician Francisco Romero Robledo.

The first documented restoration took place in 1941, when the architect Francisco Prieto-Moreno y Pardo proceeded to clean the corridor, replace three roof slabs with similar ones, repair the holes in the corridor and the chamber using stone slabs, install electric lighting to facilitate visits and maintenance, restore the area destined for offerings and place a commemorative inscription at the entrance. The most recent intervention was carried out in 2002 by architect Ciro de la Torre Fragoso, who, for conservation purposes, fixed four roof slabs with stainless steel rods and removed two pieces of graffiti. In addition, a new pavement was created in the tomb with a layer of plaster and an interior lighting system was installed to improve the in situ museum display.

The exceptional universal value of this monument lies in its anomalous orientation, which points towards the El Torcal mountain range. This unusual feature was identified by the archaeoastronomer Michael Hoskin, who, after measuring more than two thousand dolmens in the Mediterranean, documented this phenomenon in his work on the orientations of tombs and temples, thus offering a renewed perspective on the Prehistory of the Mediterranean.
