Article (June 2016) from Archaeology in Bulgaria:
The grave of a female aristocrat from the Shishman Dynasty which ruled the Second Bulgarian Empire (1185-1396) in its last few decades before it was conquered by the Ottoman Turks has been discovered during the excavations of the old church St. George near the town of Trudovets, Botevgrad Municipality, in Northwest Bulgaria.
The now defunct St. George stone church near Trudovets is believed to have been part of a medieval monastery, and still has fragments of medieval frescoes. On the archaeological site of the stone church, locals have found a marble pillar and EarlyByzantine coins from the 5th-6th century, leading scholars to hypothesize that the monastery which existed there may have dated back to Early Christian times.
The newly discovered grave of a young princess proves that the Botevgrad Valley was also part of their estates because a ring found together with the other female adornments in the funeral inventory features a monogram of the Shishman family.
