The church, known as the Trinity Church, was previously called the Nikolskaya or Nikolaevskaya, but in the parish and surrounding areas, it is still referred to as Nikola Klokovo. This stone parish building houses both summer and winter churches. The temple has three altars: one in the cold part, dedicated to the Holy Trinity, and two in the warm part, in the name of the holy prophet Elijah and the holy wonderworker Nicholas. The construction of the warm church began in 1834, while the cold one was completed in 1847 and finally arranged and consecrated in 1870. The church was built through the efforts of the parishioners, among whom particularly stood out their donations from the first guild merchant from St. Petersburg, Yegor Fyodorovich Kukano, at the beginning of the construction, and the second guild merchant Polikarp Vasilyevich Vasilyev from the village of Okultsova at its completion.

The church especially honors the carved icon of the holy wonderworker Nicholas. The parish has three chapels: a stone one in the village of Okultsova, built in 1883, a wooden one in the village of Malkovo, erected in 1885, and another wooden one in the village of Khvatovo, which was rebuilt in 1900.

The church owns land covering 63 desyatinas and 1875 square fathoms, as well as a house for the priest. The church capital amounts to 6575 rubles in bonds. The parish has 498 men and 681 women, totaling 1179 people. The village of Klokovo is located on a plain surrounded by forest owned by the church. The village has a church-parish school, parish guardianship, a library for parishioners, and a sobriety society. The clergy consists of a priest and a psalmist, with the clergy capital in securities amounting to 8729 rubles.
