Unfortunately, the exact date of construction of the church in Liachowicze has not been found yet. Approximately old wooden church was built at the end of the XVIII century. You can read about it in “In the list of Christian Catholic settlements in 1726” But the oldest document about the existence of the church can be considered the preserved Uniate metric books in RGIA from 1776 to 1801. Further, the Marmon site also has metrics for Liachowicze for 1823.
