Ilyinsky Pogost, located in Kostin Corner on the Tara River, is 25 versts from the district town and 90 versts from the provincial center. The patriarchal tax records from 1628 mention: "the church of Saint Prophet Elijah in Kostin Corner monastery mansion." However, there is no information on when and by whom this monastery was founded, or until when it existed.

According to the scribal books of the Yarapolche Volost from 145-155 years, the place is already listed as Ilyinsky Pogost, which had 5 households of unplowed widowers. According to the records from 1653, the Ilyinsky church had households of priests, sextons, and prosphora bakers, 3 households of church widowers, as well as 6 households of landowners, 101 households of peasants, and 5 households of widowers. The church's arable land consisted of average land of 6 quarters in the field, and hay was harvested in Milkovskaya Luka on the Klyazma River, 5 stacks.

No information about the reconstructions of the church in the 17th and 18th centuries has been preserved. In 1826 and 1829, a stone temple was built in place of the former wooden church at the pogost, which still exists today. This temple has two altars: the main one in the name of Saint Prophet Elijah, and in the warm chapel, in honor of the Korsun Icon of the Mother of God.

An 1644 edition of the Gospel has been preserved with the inscription: "this book of the black priest Moses, and he applied it to the Vladimir districts in Yarapolche in Kostin Corner to the Prophet Elijah on the altar for his parents and for his soul."

The parish is staffed with a priest and a psalmist. Their maintenance is ensured by the interest from the parish capital from services and sacramental corrections, as well as income from church land, amounting to up to 350 rubles a year. The priest's house is church-owned, while the psalmist has his own.

According to the general land survey plan, the lands near the church are distributed as follows: estate land, 2 dessiatins 600 fathoms, haymaking land, 9 dessiatins 1,600 fathoms, arable land, 98 dessiatins 1,548 fathoms, two-thirds of which are now overgrown with forest. Timber and firewood forests, 59 dessiatins 1,230 fathoms, totaling 170 dessiatins 236 fathoms. A land survey plan for this land is available. Additionally, Mr. Solyarsky donated 50 dessiatins of land in 7 plots, of which 31 dessiatins are various forests, and the remaining part is arable and haymaking. Finally, the parish shares 5 dessiatins of haymaking land on the Klyazma River with the church.
