The Belley Estate is an example of late pre-revolutionary architecture, built in the early 20th century. It is located in Peterhof and is now part of the estate and park ensemble. The first and actually only owner of the estate was Nikolai Nikolaevich Belley, the son of a British subject and one of the founders of the Society of Charcoal Burning Plants. The estate was designed by the famous Russian architect of French descent Hippolyte Pretro, who was executed during the Soviet era.

On the estate's grounds, in addition to a two-story mansion and service buildings, there were an ostrich farm, three ponds, two greenhouses, and a music pavilion. The regular park was planted with linden trees and flowerbeds were arranged. One of the greenhouses housed a collection of hydrangeas, which the owners were very proud of. The estate was quite impressive and perfectly suited to millionaire Nikolai Nikolaevich.

After Nikolai Belley's death in 1914, his widow, who was a blood aunt to Georgy Adamovich, and gardener Otto Martynovich Pomberg continued to care for the estate.

After the revolution, the estate was seized from Vera Belley, and in 1920 she emigrated. Gardener Otto Pomberg remained at the estate until 1941 and returned there after the war. Over the years, various organizations, such as rest homes and sanatoriums, were located in the estate, and in 1948, its buildings were converted into a warehouse for the Research Institute of Instrument Engineering. In the 1990s, the estate was unused and fell into disrepair.

Today, the estate belongs to private owners who, despite its status as a regional cultural heritage site, have repeatedly violated preservation obligations by conducting unauthorized work. This is confirmed by a number of administrative cases. The estate remains in a deplorable condition, and no necessary restoration work has been carried out.
