Bosnian Pyramid of the Sun
Bosnian Pyramid of the Sun (former Visocica), with its height of over 220 meters, is one third taller than the Great pyramid of Egypt.
Four sides of the pyramid are perfectly aligned with the cardinal points (North-South, East-West).
Measurements made by the Geodetic Institute of Bosnia and Herzegovina suggest that northern portion of the pyramid is forming geometric feature of triangle, with equal sides of 365 meters and inner angles of 60 degrees.
North side of the pyramid is oriented towards stellar north (like the Great Pyramid of Egypt), in parallel with position of the North Star.
Numerous scientific analysis suggest artificiality of the monument: satellite imagery, thermal inertia analysis that shows quick heat loss due to inner chambers and hallways; penetrating radar suggests straight passageways with 90 degrees intersections; water drainage and inner angles of 45 degrees characteristic for artificial objects.
Geo-archaeological research uncovered man-made stone blocks that form the walls of the pyramid.
