One of the most beautiful temple complexes, located in the village of Upper Nikulskoe is the temple of the Holy Trinity. The complex includes: Trinity church, temple fence, equipped with gates, as well as two small, built of brick gatehouse, which are on the corners of the fence.

The construction of the temple had at the beginning of the 18th century. It built on two thrones, one of which was the winter - in honor of St. Nicholas the Monk and the other - the summer - in honor of the Holy Trinity. In the early years of the 19th century from the north wall winter temple were found cracks that went down to the south wall. At that time it was the preserve of Musin-Pushkin Anna Nikolaevna - that's why it was notified first. In his role as guardian of the temple was Glebov Nikolai, who was descended from the ancient boyar family. These people have become fully responsible for repairs to the church.

Soon after construction work began, according to which the refectory room has been expanded, that was meant for the throne in honor of the Kazan Icon of the Mother of God. The work continued for about three years. At the end of 1806 the ceremony of consecration of the church, after which work began on rebuilding the internal decoration of the temple.

The church is a prime example centric strict five-domed temple, built in an "octagon on the quadrangle." As the dominant buildings is the main volume, made in two levels and fitted on each side of semicircles, which is crowned with a slender light octagonal onion dome and cupolas.

After some time, we have been made for the construction of single-tiered work refectory room, equipped with four pillars in the interior as well as a little bit rounded corners; then built also a small four-tiered bell tower with a miniature dome and spire. The church is completely built of brick and then plastered. The base of the temple put up made of granite boulders. As a decorative treatment of façade architectural style was chosen - "Naryshkin" baroque.

The temple is surrounded by a fence around the perimeter, built in the second half of the 19th century - it is made in the style of late classicism with a fairly clear and distinct pattern on the metal grate.

It is important to note that in the temple of the Holy Trinity for the entire lifetime of never interrupted church services, even when the owners of these lands were ruined and made the decision to sell the property. Moreover, during the Soviet era the temple was not closed, and it is precisely at this time the government waged a bloody struggle with religious beliefs, because that the greatest number of parishes have been closed or liquidated.

In the early years of the 20th century the temple was a happy event: the arrival of the icon of Our Lady gave "It is truly meet" or "Merciful", which was considered very valuable Orthodox relic .  Icon famous incredible wonders and numerous healings .  Presented icon contains three particles from the relics of the holy Martyr Tryphon, the Nile and the Sinai Horlampiya .  On the front side there is an inscription that tells that the icon was painted and consecrated on Mount Athos at the monastery of St. Andrew .  This relic was brought to our country in 1915, after which she quickly got into Trinity Church - gave it to the abbot Joseph parish .  About this man I know that during the years of Soviet power, he died a martyr's death is terrible in one of Stalin's camps .  To date, the miraculous icon is located in Rybinsk, namely in the Kazan church, where in front of her face may worship the multitude of parishioners and pilgrims .

Currently, the temple of the Holy Trinity continues fully to operate than deserves the incredible love and devotion of the villagers, who for a long time, visit this particular temple.
