Study of the Cañada Real dolmen reveals existence of other underground structures
A recent study of the Cañada Real dolmen has revealed evidence of further underground structures using geophysical prospecting.
The Cañada Real dolmen is an ancient funerary monument found in a Neolithic necropolis, located in the city of Los Molares in the province of Seville, Spain.
The dolmen has an “L” plan gallery that measures 8 metres in length, while the other side measures approximately 3.5 metres. It was first discovered in 1968 and was excavated by professor D. Juan de Mata Carriazo. Further studies in 1980 revealed a second funerary monument, the El Palomar dolmen, which was excavated by the Archaeological Museum of Seville.
Both sites date from the Neolithic period around 4000-3500 BC, when the region saw the arrival of the first agriculturalists that started the tradition of burying their dead in dolmen tombs.
A recent survey commissioned by the Spanish National Research Council (CSIC) from Extremadura, has revealed evidence of additional underground structures using Ground Penetrating Radar (GPR). GPR is a non-intrusive geophysical method that uses radar pulses to image the subsurface to investigate underground anomalies and archaeological features.
The GPR survey has identified at least two other dolmens in the vicinity of the Cañada Real dolmen, located at a depth of several metres deep. According to the director of the archaeological investigations: “the underground anomalies reflect a figure of similar dimensions to those of the Neolithic dolmen with an L-shaped plan, the typical local architecture of the prehistoric megaliths of Los Molares.” In addition, “there is another large structure buried very close to the Cañada Real dolmen that looks like a corridor-type dolmen with a chamber.”
The survey has also revealed the outline of circular features that could correspond to Neolithic type roundhouses used by the early tribal societies living near the necropolis. According to the researchers, little is known about the domestic spaces of the dolmen builders, so the discovery from future excavations could give archaeologists new information about the ancient people that lived in the Los Molares area from their material culture left behind.

A recent study, published in the journal ResearchGate, proposes that the Pyramid of Djoser could have been constructed using hydraulic lift.
The Pyramid of Djoser, also known as the Step Pyramid, is a proto-pyramid built as the final resting place of Djoser, the first or second pharaoh of Egypt’s 3rd Dynasty (2670–2650 BC) during the Old Kingdom period.
The pyramid rises from the Saqqara plateau in six steps to a height of around 60 to 62 metres, serving as the centre of a vast mortuary complex.
Due to the absence of authentic sources from the pyramid architects’ working sphere, there is currently no confirmed comprehensive model for the method used in the pyramid construction.
The prevailing theory suggests that the heavy stone blocks were transported on apparatuses such as rollers, and raised to height using a series of ramps.
In the study, a survey of watersheds near to the pyramid indicate that the Gisr el-Mudir (enclosure) has features of a check dam for trapping sediment and water. Furthermore, the topography beyond the “dam” shows a possible ephemeral lake west of the Djoser complex, and water flow inside the moat surrounding it.
The study authors explain: “In the southern section of the moat, we show that the monumental linear rock-cut structure consisting of successive, deep compartments, combines the technical requirements of a water treatment facility: a settling basin, a retention basin, and a purification system.”
Based on this finding, the study proposes that the Gisr el-Mudir and moat’s inner south section worked as a unified hydraulic system for regulating flow and improving water quality. In addition, the pyramid’s internal architecture is consistent with a hydraulic elevation mechanism never reported before.
“The ancient architects likely raised the stones from the pyramid centre in a volcano fashion using the sediment-free water from the Dry Moat’s south section. Ancient Egyptians are famous for their pioneering and mastery of hydraulics through canals for irrigation purposes and barges to transport huge stones. This work opens a new line of research: the use of hydraulic force to erect the massive structures built by Pharaohs,” said the study authors.
Please note: This study was submitted to PLOS ONE on December 7, 2023. After two rounds of review by peers, the paper was formally accepted by PLOS ONE on June 27, 2024. Since July 23, 2024, it has been the subject of new consultations and review by the PLOS ONE Editorial Board.

Constructed between 1630 and 1633 in a Renaissance-Baroque style, the Great Synagogue of Vilnius served as the religious centre of a complex of synagogues, mikvahs, and community institutions devoted to Torah study in Vilnius, Lithuania.
According to a press statement by the Israel Antiquities Authority (IAA): “The Great Synagogue of Vilna was the beating heart of the Lithuanian Jewry, which included 12 synagogues and study houses, the community council building, the home of Rabbi Eliyahu – the Vilna Gaon, Kosher meat stalls, the famous ‘Strashun’ library, a bathhouse and more.”
During World War II, the synagogue was looted, burned, and partially destroyed by the Nazis in the holocaust. Soviet authorities completely demolished the remaining structure to build a school, intending to prevent any future restoration of Jewish worship.
Only three original pieces of the synagogue survived the destruction: a door of the Holy Ark, a reader’s desk, and a bas-relief with the Ten Commandments, which are now on display at the Vilna Gaon Jewish Museum.

In a recent study conducted by the IAA, the Association of Lithuanian Archaeology, the Good Will Foundation, and the Jewish Community of Lithuania, archaeologists have rediscovered traces of the synagogue’s decorated walls and remnants of flooring with red, black, and white floral patterns that paved the main hall.
Excavations also uncovered huge water reservoirs to feed halachically pure water to the mikva’ot, and one of the giant pillars that surrounded the Bimah (prayer platform).
Dr. Jon Seligman from the IAA and Justinas Rakas from the Lithuanian Archaeological Society, said: “The magnificent remains we are rediscovering bring back moments in the life of a lost vibrant community.”
