The rich archaeological heritage of the Elhovo area is presented in independent exhibition hall. The exhibited monuments demonstrate the rich millennia culture of the area of Lower Tundzha, between Strandzha and Sakar. Extremely rare for the territory of Bulgaria are the 3 stone scepters of the bronze epoch and the only fully preserved copper ingot – pre-monetary form for exchanging and trading, owned by the Bulgarian museum institution.
