The church was built in the 12th century and existed until the 15th century. In 1884-1885, Professor I. Sharanevych and Father L. Lavretsky excavated the foundations of an unknown temple on the field of V. Figol, a resident of Krylos village, and blacksmith Moshynsky. Its name was established based on legends recorded in the 1880s by I. Sharanevych from Petro Malaniy, the sexton of the Krylos Assumption Church. This name, apparently, was only an indication of the settlement where the structure was located. A mention of a village with such a name is contained in the “Zemsky Acts,” which report that in 1458, the Halych starost Stanislav from Khodech sold for 25 hryvnias the guardianship over the Krylos Monastery and the village of Pidhoroddia, and the Annunciation to the Lviv vicar Roman from Ostapovych village. The question of the functional purpose of the Annunciation Church is still insufficiently studied. As is known, the vast majority of settlements whose names are associated with religious holidays or one of the Christian saints were founded around monasteries of the same name. In such a case, the temple itself should have originally belonged to this monastery. However, since archaeologists have not yet found any convincing evidence of monks living here, there is no reason to consider the Annunciation Church a monastic shrine for now. In 1987 and 1990, the Annunciation Church was re-examined by an archaeological expedition of the Institute of Social Sciences of the Academy of Sciences of the Ukrainian SSR under the leadership of V. Aulich.
