In XVIII century village Polonóe was owned by the family of Princes Beloselskiy. In 1618 on the high right bank of the river Polonka in the village Polonóe, the stone church in the name of the Image of the Savior Not Made by Hands was built. Inside of the church there was a chapel of the Prophet Elijah, built in 1713 by Prince Stepan Beloselskiy. In the church graveyard there were burials of the nobility.

In XIX century, Prince Aleksander Mikhaylovich Dondukov-Korsakov became the owner of the estate, and in 1875, at the entrance to the church, he erected a brick tomb for relatives.

In 1929 the church was converted into a club, and then wiped off the face of the earth.

All that is left of the church and the graveyard is a flat meadow overlooking the picturesque Polonka river with a hefty tree stump and a wooden worship cross.

Many gravestones were used as a building material and some were placed on the banks of the Polonka river to serve as steps.

The main manor house of the Princes Dondukov-Korsakov family estate was called the White Villa.

The two storey stone house was built in 1888 by architect A. A. Stepanov.

During the post 1917 revolution Soviet era the White Villa was dismantled for bricks and miraculously one of its wings survived.

In modern days with the blessing of Metropolitan Evsey of Pskov and Velikiye Luki, Archimandrite Pavel dean of Porkhov and his parishioners rebuilt the remaining wing of the White Villa into the Church of the Icon of the Mother of God "The Assistant of Sinners." Since 2007 church services have been held there.

In 2011, by the efforts of local ethnographers, the surviving gravestones of Dondukov-Korsakov Princes family members were transferred to the churchyard.

Despite the efforts to preserve these historic gravestones, there have been repeated attempts to steal the gravestone of Prince Aleksander Mikhaylovich Dondukov-Korsakov, Adjutant General and General from the Cavalry, who owned White Villa with the rest of the Dondukov-Korsakov estate in the middle of the XIX century.
