The village of Troitskoye on the Protva River, known since the mid-17th century as the property of the Dashkov princes, is linked to the history of Prince Mikhail Ivanovich Dashkov. In 1759, he married the daughter of Count Roman Illarionovich Vorontsov. After his death in 1764, the prince's widow inherited Troitskoye, where she spent most of her life.

In 1794, after a conflict with Catherine II, Dashkova was exiled to Troitskoye. Emperor Paul I, upon becoming ruler, stripped her of all positions and awards, ordering her to live in Troitskoye.

In 1765, Dashkova visited Troitskoye for the consecration of a new stone church of the Holy Trinity, which has survived to this day. A.T. Bolotov recalled that the church was majestic and adorned with magnificent iconostases.

Under Dashkova, a manor house, theater, riding school, greenhouses, and a sanatorium were built in Troitskoye. She actively participated in their design. Dashkova often spoke of her love for Troitskoye, where she wished to live and die. She engaged in many affairs, even if she had a vague understanding of them.

The Protva River surrounded the estate on three sides. The main house was connected to the wings by galleries, and nearby stood the theater, hospital, and other buildings.

In the summer of 1784, Dashkova hosted her friend Lady Hamilton in Troitskoye, in honor of whom one of the villages was named Hamiltonovo.

M.M. Dunaev and F.V. Razumovsky described Troitskoye as an oasis of enlightenment. The estate included the main house, theater, stable, riding school, greenhouse, and the Holy Trinity church, where Dashkova was buried. Under her, the estate flourished: a mill operated, fruits and flowers were grown in the garden, and the park was adorned with alleys and a monument to Catherine II.

After Dashkova's death, her heirs opened factories in the estate, which operated until 1941. With the onset of war, the estate fell into disrepair.

Today, among the ruins, the wings in the early classicism style, the arch, and parts of the park stand out. Local residents restored the Troitskaya church and care for the princess's grave. A tombstone has been placed over her remains, and candles always burn at the icon of Saint Catherine in the church. The old necropolis next to the church has also been restored.
