In the second chapter of the Biblical book of Devarim (Deuteronomy), there is mention of giants and Refaim.
The Refaim were apparently also giants who lived in Eastern Transjordan. In Chapter 3, Og the King of Bashan is mentioned; 
it says that his bed was 4.5 meters long, and 2 meters wide.
The stories of ancient giants who lived on the eastern side of the Jordan River are connected – in the eyes of hikers and folklorists –
to the unique archaeological finds in the Golan. This is the source of the term “Land of Refaim.”
The Dolmens
The term “dolmen” – an ancient Celtic word – means “stone table.”
Indeed, the dolmens look like a table with two legs and a slab of basalt stone placed on top of them. In the Golan,
more than 6,500 dolmens have been found, including entire fields of them.
The biggest dolmens found in the Golan are the Tank Dolmens. The archaeologist Claire Epstein, who surveyed the Golan after the Six-Day War, thought at first – from afar – that these structures were Syrian tanks (and hence the name).
The dolmens are considered to be ancient burial structures, built over graves that were dug into the ground.
The dolmens were built in approximately the 20th Century BCE (about 4,000 years ago).
It is noticeable that much work and energy were invested in building these structures.
Researchers have not been able to find the villages in which lived the people who buried their dead throughout the Golan.
They might have been nomadic societies that buried their dead as they traveled.
Nonetheless, building the dolmens demanded the existence of an organized society with impressive abilities of planning and executing large-scale projects.
