Grebnevo Estate, Manor house in Selskoe poselenie grebnevskoye, Russia

Grebnevo Estate is a two-storey manor house of pale yellow walls with white trim, its central block topped by a triangular pediment with a small round medallion and white columns between the upper-storey windows. A white band separates the storeys, and one section on the right is dark, as if stained or fire-damaged. The main house was built by the 1790s under General Gavriil Bibikov, and the ensemble also included galleries, pavilions and Gothic-style service buildings.

The estate's history begins in the 16th century as the village of Bokhovo, recorded in scribe books of 1584–1586 as belonging to Bogdan Belsky, armorer to Ivan the Terrible. Under Prince Dmitry Trubetskoy a dam was built on the Lyuboseevka River, creating the Barskiye Ponds. From 1781 Gavriil Bibikov, whose wife Tatyana Tverdysheva had bought Grebnevo, dismantled the old fortress and had the main house built by the 1790s; his widow sold the estate in 1811.

The estate's name comes from the Grebnevo Icon of the Mother of God, kept at the Lubyanka church in Moscow; Bibikov's 1786 summer church was consecrated in its honour. At the turn of the 19th century Bibikov ran a theatre, a ballet troupe and an orchestra led by the serf musician Danila Kashin. His granddaughter recalled summer tea parties in a garden gazebo reached by ferry across the pond.

The estate is located roughly 30 kilometers northeast of Moscow and can be visited through guided tours and special events. It is helpful to use a guide or audio guide to understand the purpose and details of all the buildings throughout the property.

The Barskiye Ponds began with a dam Prince Dmitry Trubetskoy built on the Lyuboseevka River south of the village; the reservoir had a complex shape and several islands, some of which survive. Bibikov's granddaughter recalled crossing the pond by ferry to drink tea in a garden gazebo.
