The Cheremukha River played an important role in the life of the Rybinsk region. In the 17th-18th centuries, the lands located to the southeast of the Fish Sloboda were called the Cheremosh volost or Cheremukha. Here, along the banks of the river and its tributaries, there were villages and burial sites, where one can still see monuments of stone and wooden architecture. Ten kilometers from Rybinsk, on a hill at the confluence of the Yoda River into the Cheremukha, lies the village of Mikhailovskoye. From there, following the old, now half-abandoned path to Bolshoye Selo, one can cover another ten kilometers of dirt road to reach the village of Alexandrov Pustyn. Here stands the oldest structure in the Rybinsk district, the stone Trinity Church, built around 1678. It was once the temple of a small monastery known since the time of Ivan the Terrible. In the 17th century, the monastery also had wooden churches of St. Onuphrius the Great and the Assumption of the Mother of God with a chapel of Archangel Michael, complemented by a wooden tent bell tower. In the 18th century, the wooden churches were dismantled, and in 1764 the monastery was abolished, turning the stone church into a parish church.

The Trinity Church has survived to this day with significant losses. Only the main volume remains, a tall square structure elongated along the north-south axis and covered with a barrel vault, on which three small tents are installed. Originally, the temple had a large three-apse altar part and a two-column refectory. A tent bell tower adjoined the northwest corner of the refectory. In the late 18th century, an altar in honor of Archangel Michael was built against the north wall of the refectory, part of which became the lower tier of the bell tower. In the first half of the 19th century, a porch was added to the western facade of the refectory; the floor of the church was laid with cast-iron plates, hiding the ancient brick flooring.

In terms of its volumetric and compositional solution, the Trinity Church belongs to the type of monastery refectory churches, which were already widespread in the first half of the 16th century. The refectory was used as a place for brotherly meals, where all the monks gathered. After the monastery was closed, it became a warm winter church. Such churches were especially convenient in winter when the heat from the refectory warmed the church itself. Usually, refectory churches were built as two-story buildings so that the lower floor housed utility rooms and a kitchen. However, the poor forest monastery probably did not have the means to build a two-story stone building.

The external decoration of the Trinity Church is characterized by a severe conciseness, unusual for the second half of the 17th century. The facades are enlivened only by wide corner pilasters, narrow windows resembling loopholes, and small square niches for icons. The three low tents appear disproportionately small compared to the main volume. However, before the loss of the refectory, bell tower, and altar apses, the proportions of the building were different. The former appearance of the Trinity Church was captured in drawings by the Yaroslavl local historian I.A. Tikhomirov, who visited Alexandrov Pustyn in the late 19th century. A correct representation of the original appearance of the church can also be given by the typologically similar three-tent church of the Vladimir Mother of God in Yaroslavl.
