In an August 2026 interview with LB.ua, Roman Malenkov described 2023 archaeological work on the site of the former Epiphany (Bogoiavlensky) Cathedral inside the NaUKMA campus. He says archaeologists exposed about a meter and a half of surviving stone wall and a preserved floor — conditions that typically imply an underlying crypt.

Malenkov told the paper historical sources and 19th-century research record burials beneath the cathedral, and argued one of the crypts could contain hetman Petro Konashevych-Sahaydachny (d.1622). He says the privately organised excavations were stopped by the university’s leadership after several weeks; the trenches were filled with sand and covered with asphalt.

Malenkov and the city’s Department for Protection of Cultural Heritage say they attempted further work in 2024–25 and had funding, but access and institutional disagreement with NaUKMA’s administration have prevented new digs. The interview frames the episode as a lost archaeological opportunity on a sensitive Podil site; LB.ua has the full conversation and photographs.
