In 1882, near the northern border of Dibrova, the parish priest of Zalukva village, Father Lev Lavretsky, together with Lviv historian Isidor Sharanevych, discovered the massive foundation of a four-pillar, three-apse stone church.

At the beginning of the 20th century, O. Pelensky repeatedly uncovered the foundation in several places and subsequently published a somewhat different foundation plan. Based on the toponym Kyrylivka, the researcher named the church Kyrylivska and considered it a monastic temple.

In 1981-1984, the ruins near Dibrova were investigated for the third time by a detachment of the Galician archaeological expedition of the M. Krypiakevych Institute of Ukrainian Studies of the Academy of Sciences of the Ukrainian SSR, led by V. Aulikh.

Reports are stored in the archive of the Field Committee of the Institute of Archaeology of the National Academy of Sciences of Ukraine.

Findings are in the collections of the M. Krypiakevych Institute of Ukrainian Studies of the National Academy of Sciences of Ukraine.
