In hilly Tyulbe Park, a 15-minute walk northeast of Kazanlâk's centre, is one of the archaeological finds of the century: a brilliantly frescoed, 4th-century-BC tomb of a Thracian ruler. Discovered in 1944 during a bomb shelter construction, it's now a Unesco World Heritage site.
Along the dromos (vaulted entry corridor), a double frieze depicts battle scenes. The burial chamber is 12m in diameter, and covered by a beehive dome typical of Thracian 3rd to 5th centuries BC design. The dome's murals depict events such as a funeral feast and chariot race.
