At the Pyramid of Perperikon there are at least 3 large rock-cut reservoirs. The reservoirs are cut clean inside the rock.
One reservoir is located at the summit of the pyramid on the plateau we see today. Until the 1920s it used to fill up with water from an underwater source. The supply of water was disrupted by an earthquake. At some of the pyramids of Plovdiv we find a similar pattern of water sources coming out at the summit of the pyramid.
In Perperikon the top reservoir acted as a water storage. The water was drained towards the East section of the site by channels cut in the stone. It is unclear when these channels were carved in the rock. Perperikon is a megalithic site with a long history. It has been inhabited at least since Thracian times used through to the Middle Ages. It was transformed at each epoch including today as the restoration work to promote tourism is focusing on the reconstruction of the Medieval period to the detriment of earlier periods.
The top reservoir is rectangular in shape. It is 12 by 9 metres and is estimated to be 6 metres deep. In the earliest incarnation of the site when Perperikon was a step pyramid, it was probably the central piece of the site. It tells us about the close connection between pyramids and water.
Water emanates from the Earth. It is the expression of Earth’s energy coming to the surface. Water is also connected to the Moon.
The top reservoir of Perperikon tells us that pyramids were built in specific locations. It tells us about the age of the pyramid by its size and position. The reservoir was built during the earliest phase of construction at the site as it could not have been added at a later stage. The site was probably built around the reservoir. Also, the technique required to carve out such a reservoir was not available to any known historical civilisation for which we have any records. Neither the Thracians, Romans or later civilisations had the technology to build such a reservoir. And there is no record of it being built and there was no impulse to create such a reservoir on top of the plateau.
There are at least 2 other rock-carved reservoirs on the megalithic site of Perperikon.
There is also a neighbouring hill that hides megalithic formations but it has never been cleared. Maybe it will provide a base for comparison and the opportunity to better understand the ancient part of the site of Perperikon overall.
