One of the lesser-known estates in the Moscow region is the ancestral estate of the Counts Olsufiev, located in the ancient village of Ershovo. Originally, these lands belonged to the boyars Saltykov, but during the reign of Catherine the Great, they passed to the Counts Olsufiev. In 1764, Count Adam Vasilyevich Olsufiev married Maria Vasilyevna Saltykova. The bride's father, the head of the police of the Russian Empire, saw in the count a worthy match for his daughter and gifted the young couple the village of Ershovo as a dowry. Since then, these lands became the property of the Counts Olsufiev.

Count Vasily Dmitrievich Olsufiev was an enterprising man, held important state positions, and was friends with Tsarevich Alexander Nikolaevich. Among his guests was even Alexander Sergeyevich Pushkin. For such a social figure, a corresponding estate was required, and the construction of the new manor was led by the renowned architect Afanasy Grigorievich Grigoriev. Soon, an architectural complex in the style of late Moscow Empire emerged, including a palace, wings, a church, and a library.

After the founder's death, the estate passed to Alexei Vasilyevich Olsufiev, the last owner of the estate. During this time, the poet Afanasy Fet frequently visited the estate, as he was a long-time colleague of the new owner. Count Olsufiev took pride in this friendship and immortalized the poet's stay in Ershovo with a marble plaque.

With the advent of Soviet power, the estate was confiscated, but unlike many others, it was not completely destroyed and became a museum. Although much was lost, a significant part of the estate has been preserved and restored. Today, Ershovo is a museum complex and a nature reserve.
