The church St. Nikola-Old in the town of Lom (North-western Bulgaria) was constructed during the reign of the Bulgarian king Mihail-Asen (1246-1257). It was destroyed several times and then restored by local patriots.

In 1760 a monastery school was opened here - one of the first in the Vidin diocese, where the alphabet, the breviary and the psalter were taught.

A part of the icons were painted by icon-painters from the Debar artistic school. Some of the icons were brought to the church St. Nikola-Young.
