In the 16th century it was seriously damaged during the Livonian War, it lost its roof and most of the ceiling. During this period, it was managed by Polish Catholic priest Marcin Mierzejowski. In the first half of the 17th century, the building was still in ruin, only the tower was rebuilt with a wooden structure. Another destruction was caused by the Great Northern War at the beginning of the 17th century, but from 1734, gradual repairs were begun, continued also in the 19th century.

The walls of the nave and chancel were pierced with narrow and long, lancet windows.
