The results of the 2010 salvage and conservation archaeological research in the territory of the Bolgar fortified site, conducted in the construction zone of the so-called “Memorial Plaque” (excavation trench CXLVIII) are presented in the article. The horizons referring to the second half of the pre-Mongol period (the 11^th to first third of the 12^th century); the earlier (the mid-13^th through to the early 14^th century), and the later (the mid-14^th – early 15^th cc.) Golden Horde periods have been recorded on the site. A few constructions referring to different periods have been opened, which can probably be regarded as the remnants of a 14^th century homestead. Remnants of a small production furnace for melting non-ferrous metals and a kiln have been identified. Traces of bone-carving production have been found. Numerous fragments of pottery dated to the Golden Horde period have been revealed. Of particular interest is a Celadon dish with hieroglyphic inscription, probably a Korean-made one. The finds of copper and silver coins date from the mid- to the second half of 14^th century.
