Heraclea Sintica is an ancient city in Southwestern Bulgaria, the ruins of which are located on the land of the village of Rupite, Petrich municipality, on the southern slope of the volcanic hill Kozhuh. It is located 2 km from the temple of Vanga in the area of Rupite and 10 km from the town of Petrich.

Just before the town of Petrich, rise the rugged slopes of one of Bulgaria's most interesting geological formations. The Kozhuh Planina is too low to class as a mountain but is the most spectacular remains of the crater of a volcano whose last eruption was a million years ago. Mineral springs abound here, too, filling the air with steam and the smell of sulphur.

In the past two decades the Kozhuh Planina has been the witness of the increasingly popular cult of a local blind clairvoyant, Vanga, who spent her last years in the nearby Rupite area.

In ancient times, the city was the center of the region of Sintika, inhabited by the Thracian tribe Sinti. Heraclea Sintica was located near the village of Rupite, after the accidental discovery of a large Latin inscription in 2002. In essence, this is a letter from Emperor Galerius and Caesar Maximinus Daya in 308, in which the rulers addressed the Heraclians in response at their request to restore the lost city rights. In 2005 was published another inscription mentioning Guy Lucius the Scotsman and the Heraclian. With it he proves convincingly that this is Heraclea Cynthia.

Since 2007, the archeological excavations of Heraclea Sintica have begun with cooperation with Petrich Historical Museum. Archaeological excavations have shown that the city had an intense life, it was modern. Heraclea Sintica still impresses its researchers and visitors today. The representative buildings of the ancient city were built with great elegance, the urban plan was built according to the principles of the Hippodame system.

In Heraclea Sintica, all you will see is what its ancient inhabitants left it. The discoveries are only being strengthened and preserved. This means that your foot can step on a street stone at the age of 2300.
