The Trinity Church, also known as the Ryazanov Church, was built in the southeastern part of the city at the intersection of what was then Sennaya Square and Siberian Avenue, now known as Kuybyshev Street. Construction took place from 1814 to 1854 with funds from the head of the Yekaterinburg Old Believer community, merchant Y.M. Ryazanov.

The church, a significant monument of classicism in the city, has a three-part structure: a bell tower, a refectory, and the church itself with a semicircular apse. Above the church part rises a massive drum topped with a dome featuring semicircular lanterns. Small decorative domes are located at the corners of the square base.

The centers of the side facades of the church part are highlighted by entrance porticos with four columns in the Ionic order, complete with pediments. The lanterns at the base of the dome and the cubicles on its drum add additional scale, harmonizing the church with the surrounding buildings. The main western entrance is located at the base of the bell tower and is accentuated on the facade by a portico with two pilasters. The three-tiered bell tower is topped with a dome.

The volumetric-spatial composition of the building developed from the cubic volume of the Old Believer prayer house. Architect M.P. Malakhov not only organically integrated new architectural elements into the existing volume of the house but also solved the engineering task of transferring the load from the dome to the walls. Massive pilasters, located at the corners of the church's square base, were added from the inside to the previously laid walls.

In the interior, the sails visually rest on the pilasters but are not structural elements. In reality, the supporting ring of the drum is held up by spring arches that perform the function of squinches. Thus, the task of covering the previously built prayer house with a dome was solved.

The bell tower, built between 1850 and 1854 by architect K.G. Tursky, does not create a sharp dissonance but bears traces of the decline of the Nicholas era, and the paneling of such a large structure looks naive. The entrance portico from the pilasters appears quite modest. The side capitals, made according to the latest design, as well as the details of the bell tower, seem somewhat small compared to the majestic drum of the central dome.

In the 1930s, when the church was adapted for a club, the monument lost its domes and the two upper tiers of the bell tower. The modern dome finishes of the church and bell tower, as well as the new altar apse, which does not correspond to the scale of the church, are the result of incorrect restoration and reconstruction carried out in the 1990s.

In the interior of the building, the refectory hall is covered with a flat suspended ceiling, which was closed with a false barrel vault at the end of the 20th century. In the church itself, the spherical dome on decorative sails is pierced with high windows and a tier of lanterns. The furnishings that decorate the interiors of the church were made in the late 20th and early 21st centuries.
