We usually associate estates with the central part of Russia or Crimea, but they were also common in the Far East. They were mainly acquired by local and visiting merchants who became wealthy from logging, mining, fishing, and trade. Among the owners of Far Eastern estates was Julius Brinner, the grandfather of the famous actor. However, only one estate has survived to this day, specifically the ruins of the Yankovsky Castle.

Mikhail Ivanovich moved to the Far East in 1874 and successfully engaged in gold mining. On Askold Island, 50 km from Vladivostok, he established a nature reserve, brought in pheasants, bred spotted deer, and strictly controlled their hunting. Mikhail Yankovsky was also interested in archaeology and discovered household items of people who lived in the 8th-3rd centuries BC near the mouth of the Narva River. After his death, the estate was inherited by his son.

The son decided to radically rebuild the estate by erecting a massive building. The work began in 1918, when the country was already in the midst of the Civil War. Yankovsky was aware of the pogroms of estates in the central part of Russia but hoped that this would not happen in the Far East. Although there were no pogroms for a long time, gangs of hunhuzi periodically attacked the estate. Therefore, the new estate was built as a defensive structure and was named the Knight's Castle.

However, Yankovsky did not have time to live in the castle, as he suddenly died in 1919. The estate was left abandoned, gradually deteriorating, and today it represents ruins in the Far East. The pheasants brought here in the 19th century are now rarely seen.
