Trinity Church was built in Dolginovo in 1870. in the retrospective Russian style characteristic of that time. White brick was used in the construction of the temple. In its image and shape, this shrine is more reminiscent of a voluminous dome with semicircular protrusions. In the very center, a dome rises majestically on an octagonal high drum. The sides of that drum are separated by round arched window openings. Trinity Church also has three entrances, which are decorated with arches and unique ornaments of the pseudo-Russian style.
