In the early 17th century, Avchurino belonged to the voivodes Yakovlevs, and by the end of the century, it became the property of the chamberlain F.A. Khitrovo. From 1716, the estate passed to the Attorney General of the Senate, Count P.I. Yaguzhinsky, and from 1736, to his daughter’s husband, Prince S.V. Gagarin, who later managed the Tula estates of Bogoroditsk and Bobriki, owned by the son of Catherine II and Count G.G. Orlov, Count A.G. Bobrinsky. Until 1792, the estate remained in the hands of their heirs. Then, until 1818, the estate belonged to State Councilor D.M. Poltoratsky, who organized a model farm there. Until 1842, it was owned by his widow A.P. Poltoratskaya (née Khlobnikova), and until 1861, by their son, the famous bibliophile S.D. Poltoratsky, who significantly expanded his grandfather P.K. Khlobnikov's library. The last owners of the estate before 1917 were landowners M.F. and O.N. Goncharov.

Sergey Dmitrievich Poltoratsky was so passionate about books that he decided to build a Gothic house-library for his rapidly growing collection. By that time, the main house from the mid-18th century had already fallen into disrepair, and the family moved into the new building, most of which was filled with tall bookshelves. Later, the rich collection of books was transferred to the Rumyantsev Museum.

The "Gothic house," built in the 1840s and 1850s, remains the main attraction of Avchurino. Its two-story stone building, which over time has been surrounded by wooden extensions, was cleared of later additions during the Goncharovs' time, who renovated it in 1913.

The four-story angular tower, located in the park part of the house, served as a viewing platform for the owners. It gives the building a sense of completeness and a castle-like appearance. Through the broken windows, one can see the metal frame of a spiral staircase with large curls leading to the upper tier, where an observatory was located after 1917. At one time, the capital architect V.P. Stasov worked for the Poltoratskys in Avchurino. According to his design, architect L. Pelli built an Empire-style gazebo next to the house in 1818.

Today, only the portico with seemingly suspended columns remains of the magnificent pavilion, giving it the appearance of a sad curiosity. The old Nikolskaya Church from 1716, reconstructed by Stasov in 1820 and 1833, has also not been spared by time. Its ruined remains are hidden in dense thickets of trees to the left of the house.

In addition, several outbuildings have survived on the estate; a landscape park from the late 18th and early 19th centuries, predominantly linden, with a pond; an oak avenue about 2 km long, crossing the Red Bridge built in 1823.

Notable visitors to the estate included N.M. Karamzin, Emperor Alexander I in 1816, and in 1837, future Emperor Alexander II along with his tutor, poet V.A. Zhukovsky.

According to the inventory of the 1840s, the estate had more than 50 buildings and structures, including greenhouses, a horse riding arena, park pavilions, a bridge, and a huge cellar. Currently, the remaining buildings are in a state of emergency.
