In 1921 Miadziel became a part of the Second Polish Republic, in 1927 the monastery was returned to the Carmelites. They began the restoration that lasted up to 1941. During the Second World War, the monastery supported the Home Army. Its buildings were burned down in 1943 by the Soviet partisans, after the war the church was used as a warehouse for agricultural machinery.

In 1982 archaeologists Zianon Pazniak and Michael Chernyavskiy (archaeologist) began excavations near the church and discovered a massive stone foundation and a fragment of a brick wall, that presumably was the Uniate church of the XVII century.

The church was consecrated again in 1990.
