This paper describes a sacred triangle in a landscape of prehistoric England that was constructed around 2400 BC. The triangle consists of three henges: Stonehenge, Woodhenge and Bluestonehenge. In form, it is a right isosceles triangle lined in respect to E-W and N-S lines.
This paper approaches the most well-known sacred landscape structure of prehistoric England with the background of the recent research of analogue structures of pre-Christian Slavs. The ancient Slavs positioned their sacred sites in a tripartite structures (Pleterski 1996) that were related to the central Slavic myth of a divine battle between a thunder god and his underworld opponent (Katičić 2003-2011). A substantial number of sacred triangles has already been described in Croatia, Slovenia, Austria and Germany (Pleterski 1996; Belaj 2007, Đermek 2010). These triangles probably give enough evidence to support the claim that the ancient Slavs positioned their sacred sites in a way that the angles between lines connecting pairs of sites have astronomical significance (usually refer the zenith and azimuth angles which the sun takes through the annual cycle). Very often in the observed triangles among some of the sides appears the ratio of 1:√2. There exist some indications that the distances between sacred sites were also important. They might have been measured using the projections of right isosceles triangles on the horizontal plane (Đermek 2012, 2013).
