Bulgaria's archaeological expedition TEMP started its new excavations in the Valley of Thracian Kings at Ploska Mound.
The information emerged from its chief, Dr Georgi Kitov. The archeological site is believed to hide in its bowels an unexplored Thracian shrine.
It is too early to be able to predict what we will find, Kitov said. All of us have higher expectations, given the last expeditions' results, he explained.
TEMP is famous for discovering some of the most sensational Thracian finds over the last several years. The team of Georgi Kitov has uncovered several Thracian tombs in the Kazanlak Kettle, which gave it the name Valley of Thracian Kings.
Last summer, the expedition discovered the sepulchre of King Sevt III, a mighty Thracian ruler.
