Ryabovo estate, Historic estate in Vsevolozhsk, Russia.

Ryabovo estate is a former noble estate in Vsevolozhsk, now part of the town. Its main building is a large, light-colored multi-story structure with a lower base, a taller central block, and a flagpole on the roof; a lower wing with an arched entrance adjoins it on the left. The estate grounds include Rumbolovsky Park and several preserved buildings.

Ryabovo estate arose in the early 18th century in Shlisselburgsky County, on the site of the Finnish village of Rääpyvä. In 1774 Baron Johann Freedericksz moved the estate centre to Rumbalovo Hill, built the first manor house and drained the surrounding forests. The Vsevolozhsky family bought it on 25 May 1818 and held it until 1918.

The estate's name comes from the Finnish village of Rääpyvä, on whose site it arose in the early 18th century. Its Lutheran church, the 400-seat Kirkko of Saint Regina built by Baron Johann Freedericksz in 1778, became the centre of the Ryabovo parish. In the 1770s Freedericksz drained the surrounding forests and brought pedigree dairy cattle, and local historians credit him with starting cheese-making on the estate.

The estate is a protected federal cultural site where visitors can examine the buildings and grounds from the outside. Comfortable shoes are recommended since you will walk around the property to view the structures from different angles.

Baron Johann Freedericksz drained the surrounding forests: a main canal about 8 km long and 4 m wide was cut toward Toksovo, fed by small channels totalling some 120 km. Iron ore found in the bogs during the digging was smelted on the estate.
