The article summarizes the information about 13th-century monuments in the borderlands of Old Rus and Poland. It publishes the archaeological data from excavations at Chełm and Stołpie, including the palace and the stone tower on a high platform, which the author interprets as a monastery. The architecture, building technique and the finds show that the influence of the Rus-Byzantine culture on the technologies and the artistic tastes was quite strong. The monuments flourished vividly yet briefly under Prince Daniil Romanovich, when Chełm became the capital of the Principality of Galich.
