It was built as a temple in the 4th century BC and later used as a tomb.
[1] The temple has a long and wide entry corridor and an antechamber, a semi-cylindrical room supported by an elegant column.
The central room is circular in shape, supported by a beautiful polished Doric column ending with a large disc symbolizing the sun.
The tomb's columns represent Thracian beliefs about the universe and the creation myth.
Archaeologist Georgi Kitov discovered the tomb in 1996.
