The Church of the Holy Trinity (Belarusian: Касцёл Святой Тройцы; Polish: Kościół Trójcy Przenajświetszej, Lithuanian: Gervėčių Švenčiausiosios Trejybės bažnyčia) is a Roman Catholic church in Hyervyaty, Grodno Region, Belarus.

[3] Gradually it fell into decline and in 1621 Eustachy Wołłowicz constructed the new wooden church.

However, some sources claim that the design was created by Ignatiy Olshansky, brother of a local priest.

Lime was mined near the Losha (river) [ru], to make limestone more solid thousands of eggs were bought from local farmers.

Mostly the funds for construction were donated by Vazlav Domeyko and his mother Anjela, nee Naruszewicz.

The walls of the temple are cut through with narrow lancet window openings in niches.
