The most comprehensive records about Halych are found in the Hypatian Codex of the Primary Chronicle. The Old Halych is also being referred to as Princely Halych (, Knyazhyi Halych) in some Ukrainian sources in order to distinguish it from the contemporary city. Today Old Halych as a settlement of the Old Ruthenia (Rus) is an archaeological landmark on a territory of Ivano-Frankivsk Oblast. Located in confluence of Dniester and its tributaries, the Old Halych appeared on the basis of several early settlements and trading sites that in 12–13th centuries were merged into one urban-like system. The central part of the human settlement with the Dormition Cathedral and princely chambers was fortified with powerful vallums and moats and was located over Lukva River (Dniester's tributary) at the place of contemporary village of Krylos.
