Khovrino, known today as "Grachyovka," is a suburban estate that belonged to the Tretyakov-Khovrin family in the 15th-16th centuries.

The history of the estate begins in the 15th century when the Surazh merchant Stefan Khovra (Khovrin), one of the wealthiest people in Moscow at the time, acquired a landholding on the Likhoborka River.

His son, Grigory Khovra, was also a wealthy merchant and around 1405 built a stone church in Simonov Monastery, which was a significant event as there were few stone buildings in Moscow at that time.

The wealth of the Khovrins allowed them to acquire numerous estates, including the village of Khovrino in the northwest of modern Moscow. However, little information about life in Khovrino during those times has survived.

It is known that at the end of the 16th century, Vasily Tretyakov-Khovrin built a church of St. George the Great Martyr in the estate, which was destroyed during the Time of Troubles.

In 1700, by decree of Peter I, the Khovrino estate was transferred to General Field Marshal Count Fyodor Alexeyevich Golovin, a descendant of the Khovrins and a comrade of the Tsar. After his death, the estate was inherited by his widow, who built a stone Znamenskaya church at the old cemetery.

Under the Golovins, a regular axial layout of the estate was established, a linden park and a fruit garden were planted. The estate was surrounded by village streets, and the church was located to the right of the manor buildings. Since the late 15th century, local residents were buried in the cemetery surrounding the church.

In 1811, the estate was purchased by Prince Obolensky. In 1812, during the war, Khovrino was looted and burned, and the Znamenskaya church was desecrated by Napoleon's soldiers.

After the war, Obolensky was unable to restore the estate and sold it in 1818 to N.A. and G.D. Stolypin. They revived the estate, changing its architectural appearance, created a pond on the Likhoborka River, and made the park more compact.

In 1859, the estate was bought by Moscow millionaire Yevgraf Vladimirovich Molchanov, and later it became the property of merchant S.E. Panov.

After Panov's death, the estate was acquired by first-guild merchant Mitrofan Semyonovich Grachev, who transformed the estate over several years: he renovated the park and outbuildings, and by 1900 built the manor house that has survived to this day. Grachev's name became attached to the name of the locality.

Khovrino is associated with many figures of Russian culture. In 1887, P.I. Tchaikovsky visited here, V.A. Gilyarovsky and A.N. Tolstoy came here, and V.Ya. Bryusov spent almost ten years of his creative life here.

In 1918, the estate's owners were expelled, and the buildings housed the labor faculty of the Petrov Agricultural Academy. In 1928, a sanatorium operated here, and during the Great Patriotic War, a hospital.

Since 1947, the main house of the Grachyovka estate has housed a hospital, transferred to the Moscow Regional Clinic of Physical Therapy. After 2004, it has been called the "Moscow Regional Clinical Center for Restorative Medicine and Rehabilitation."

In 1868 and 1870, a church of the Icon of the Mother of God "Znamenie" was built near the manor house. It suffered greatly from a fire and was decapitated, but it was restored in ten years. In 2005, the church was consecrated and is now active.
