The brick well of St John of Dukla was built in 1748-1755 in the southern courtyard of the former Bernardian monastery in Lviv. Its construction was linked to the beatification of St John of Dukla in 1733. In 2019, the Polonica Institute began work on the site. Laser scanning of the well was then performed. Work continued in 2021 when an assessment of the state of preservation and surface cleaning was undertaken.
