 During our own in-depth, long-term investigations into the possibility of our small planet, once being home to possibly multiple developed civilizations, each met cataclysm, thus each lost civilizations, as far as mainstream academia would accept, civilizations far more advanced than will ever be academically shared. Never even considering the possibility that one was indeed once responsible for the many inexplicably precise yet enormous ancient ruins found all over the world. We recently did an expose regarding the Bosda Caves. Located within Turkey, we covered the many ancient tool marks present within the caves. It was an ideal place for us to launch a pursuit into whether we could identify multiple lost civilizations. We pursued the identification of signature features within and amongst the many enigmatic stone-cut scars left by ancient technologies once used to create these incredible sights. In doing so, we identified a signature within the block building of one specific civilization, whose ruins dot Greece, Egypt, and far beyond, whose signature also present at this circular mound. Discovered by mainstream archaeologists a while ago, yet regardless Greece's culture ministry, warning against overboard speculation that an ancient artificial mound being excavated could contain a royal Macedonian grave or even Alexander the Great, the mainstream awareness of the site it seems was successfully suppressed. Regardless, due to our own independent investigations into a civilization who once constructed a number of ruins still unexplained identifying their signature present at the site, it is unquestionably an ancient structure of a now lost and suppressed civilization. Now known as the Castatum, it was intriguingly adorned with a pair of sphinxes whose heads are missing, alas we have previously addressed this mass destruction with many other sphinx heads destroyed in an effort to suppress Anubis as its true identity and the sphinx's true canine origins, yet alas the main stonework is the smoking god. The compounding factors indicating that this site was once built even quite possibly by the Great Pyramid builders due to the addition of sphinxes, yet it has been successfully stifled from mainstream view. These headless sphinxes clearly of a canine nature, and as we have previously postulated in regards to the great sphinx of Giza, was in fact once depicted as the head of Anubis, and the water erosion theory, a convolution in an effort to hide the fact that the great sphinx once rested within a great lake, namely Anubis Lake, yet I digress. The circular structure within Greece may have indeed once been built by this same once inexplicably advanced ancient civilization, yet alas any academic study funded by mainstream institutions will never accept or even consider the possibility of any advanced civilization regardless of the precision evident in their stonework, once anywhere as close or even more advanced than us today ever having existed. This advanced yet most likely claimed as Greek ruin may have indeed been used by said characters as their tombs as claimed, unfortunately however said tomb is also often claimed as their handy work as well, regardless of the inexplicable features present upon all these sites. Whether claimed as Greek or Roman, the size and indeed precision of some of the blocks often present are far out of their capabilities, yet these mainstream conspiracy theories remain the status quo regardless of said evidence. It is a system of denial and process, and we think, for good reason, although argued as the burial site of Alexander the Great, the signature features never lie, allowing us, no matter how controversial, to date this relic to a forgotten time within history. It is a debate and a site which we find highly compelling.
