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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
