Trigorskoye is a museum estate that belonged to the landowners Osipovs-Wulfs. The estate got its name due to the features of the local landscape: it is located on three wide hills, where the Voronich settlement with the family cemetery of the owners and the village of the same name, which arose on the site of an old settlement, are also found.

The estate was founded by Colonel of the Guard Maxim Dmitrievich Vyndomskiy. In 1762, Catherine II granted him lands in the Yegoryevskaya province, on which the estate was built. In 1813, the colonel's daughter, State Councillor Praskovya Alexandrovna Osipova-Wulf, settled in Trigorskoye with her family. The estate was often visited by famous writers, including Alexander Sergeyevich Pushkin, who was a friend of the family.

In the early 1820s, the estate was located in a reconstructed building of a former linen factory. It was a long single-story structure, clad in unpainted boards. In 1918, the house burned down, but in 1962 it was restored using the remaining materials.

Today, in the Trigorskoye house-museum, you can see recreated rooms: the living room, study, library, and girls' room. Next to the house, a bathhouse was built, which served not only for washing but also as a guest house and a place to relax in the heat. Each room retains memorial items: original books, paintings, furniture, and personal belongings of the owners.

The landscape park of Trigorskoye, created by M. D. Vyndomskiy in the 18th century, is a masterpiece of park art and an important part of the museum complex. The park is full of alleys and paths, there is a gazebo, three ponds, benches, and a glade surrounded by linden trees, where dances once took place. The park has many memorial sites associated with Pushkin's visits, such as "Onegin's Bench" and "Tatiana's Alley."

The park also features original sundials, where the shadow from the gnomon falls on ancient oaks that mark the time. The oak that shows noon is called the "solitary oak" and is considered to be the very oak from the poem "Ruslan and Lyudmila." It is now surrounded by a chain, albeit not a golden one.

During his exile in Mikhailovskoye, Pushkin often visited the Osipovs-Wulfs in Trigorskoye, located on the banks of the Sorot River. Now, a kilometer from the estate lies the village of Sharobyki.

Pushkin remembered the estate fondly, calling it "a refuge, adorned with the radiance of the muses." He met the Osipovs-Wulfs family in 1817, after graduating from the Lyceum. The poet dedicated several poems to the estate's hostess, Praskovya Alexandrovna. Her daughters, Anna and Yevpraksia, considered themselves prototypes of the heroines from the novel "Eugene Onegin."
