In the summer of 2004, during archaeological excavations at the Svetitsata mound near Shipka, a tomb was found. It was made of stone slabs and presumed to contain a royal burial dating from the middle or the second half of the 5th century BC.
It was at this archaeological site that a unique gold mask was uncovered. Weighing 690 g, the funerary mask is almost ten times as heavy as the ones excavated in Mycenae and Trebeniste. The archaeologists also found a bronze armour, an icon sword, arrow and spearheads, as well as red-figured and silver vases.
Scholars consider the armour to be a unique find. Several armour pieces of similar make have been found so far, but this is the first time ever that a finding reveals how the pectoral and the back plate were linked.
