Vorontsov Estate, Bykovo, Federal heritage manor in Bykovo, Russia

The Vorontsov Estate in Bykovo is a red-brick manor with white stone trim, its central section rising above the wings and topped by a jagged roofline. A stone balcony with a balustrade sits above three arched openings, and paired columns frame three doorways at ground level. The wings have tall windows with white surrounds and recessed arches below, and the building stands behind a paved terrace.

The village of Bykovo is first mentioned in the will of Dmitry Donskoy, drawn up before the Battle of Kulikovo, though other sources place it under Ivan the Terrible. Voivode Illarion Vorontsov received it from Peter I; in the 1760s Catherine II granted it to General Mikhail Izmailov, who began the stone ensemble. In the early 1840s Ivan Vorontsov-Dashkov had Bernhard Simon rebuild the main house.

The estate's second name, Marino, honours Maria Alexandrovna Naryshkina, wife of General Mikhail Izmailov, who died in 1780; the Vladimir Church was built in her memory. The name Bykovo itself is thought to come from a cattle-driving point whose meadows fattened livestock bound for Moscow. The church facade carries bas-reliefs of the couple's patron saints.

The estate lies in the village of Bykovo, Ramensky district, southeast of Moscow, and the grounds and adjoining park cover about 30 hectares. The main house stands on a hill raised from soil dug out for three ponds, so paths climb and can be muddy; wear sturdy shoes. The church of the Vladimir Icon and the 1830s bell tower stand nearby.

The north facade's attic and the south side carry the Vorontsov-Dashkov coat of arms: a shield with an angel and a cannon above, lilies and roses below, and the Latin motto "Semper immota fides" (faith never shaken). The Swiss architect Bernhard Simon gave each of the four facades its own design in the 1840s.
