All owners of the estate were influential and respected individuals. Among them was N.I. Maslov, a senator and high-ranking official, who began to arrange the Istomino estate. The village was ideally suited for creating a park: a high hill above the river opened a panorama of the surroundings with villages, meadows, and groves. Within the estate, it was possible to dam a ravine. Landscape parks were becoming fashionable, and ponds, as a stable element of Russian parks of that time, were actively used. A national style of natural gardens was forming. There is no doubt that the construction of the house and the main landscaping of the estate took place under Maslov.

To ensure the successful functioning of the park and the estate territory, a drainage system was developed, which has survived to this day, although it has significantly deteriorated. This system of ditches and mounds allowed excess water to be drained from the park into the ravine. In the ravine, planted with shrubs and separating the estate from the village, ponds were arranged. They cascaded down to the Tarusa River, their bottoms were paved with slabs and bricks, and they were fed by springs and the drainage system. To further elevate the park and estate above the adjacent field, the architect created artificial terraces of four steps descending to the river, making the elevation more dominant over the surroundings.

Thus, before starting to plant trees, arrange glades, alleys, pavilions, and grottos, significant work was done to change the landscape. The general outlines of the park have been preserved to this day. Several elms, poplars, and linden trees, about 200 years old, grow on the estate's territory. Thanks to these old-timers, one can see the layout of the old landscape park.

Maslov's grandson, Nikolai Zakharovich Khitrovo, and his wife Anna Mikhailovna Khitrovo (Kutuzova) continued the transformations in the estate, and during this period it reached its highest bloom.

The new owner of the estate, Grigory Andreevich Bykhovets, was also inclined towards enlightenment, refined activities, and organizing new crafts. Although many of his projects remained unfulfilled, and he eventually went bankrupt, his active work influenced the peasants and local nobility.

The Vasilchikovs, who bought part of the estate in 1837, used the estate as a summer residence and entrusted the management of the farm to managers. Soon the estate was mortgaged and often subjected to inventory, and the owners did not engage with it.

In the 1880s, Istomino passed to a new owner, a former peasant from the village of Lozhkino, Zakhar Mikhailovich Likhomanov, who became a merchant and manufacturer in Tarusa. He was highly respected for his charity.

To this day, a stone two-story house from 1798, belonging to Alexandra Nikolaevna Khitrovo, has survived. The school that was located here is now closed. Only ruins remain from the grotto opposite the house. However, the Church of the Assumption of the Blessed Virgin Mary, built in 1725 by Ivan Petrovich Tolstoy (great-grandfather of Leo Tolstoy), has recently been fully restored and is now operational.
