Tholos de El Romeral is one of the most important examples of early Bronze Age architecture in southern Europe. It is a megalithic burial site built circa 1800 BCE. It is one of three tombs in the region, the others being Dolmen de Menga and Dolmen de Viera, both situated to the south west.
In 2016, the dolmens of Menga, Viera, and El Romeral were all inscribed as a UNESCO World Heritage Site under the name 'Antequera Dolmens Site'.
Tholos de El Romeral is a chambered tomb covered by a mound. It consists of a long corridor with drystone walls made of small stones and a ceilings made of megalithic slabs. The corridor culminates with two consecutive round beehive-like chambers. The larger chamber has a diameter of approximately 4.20 metres and has corbelled walls built in the same way as the corridor, projecting inwards and culminating in a megalithic capstone. The floor of the corridor and main chamber are made of packed earth. The second chamber is linked to the first by a rectangular corridor (and is not accessible to the public). It has a diameter of approximately 2 metres, contains a stone slab bier, and the floor of the small room is covered with stone slabs. Bones and grave goods were found within the dolmen.
Although it is believed that these megalithic buildings had different uses (tombs, temples, etc.) the Romeral Dolmen is certainly a burial site because human remains, shells, and two types of ceramics were found within it.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
