In the 15th century, the village of Lyubun was granted to the famous princes Odoevsky and Vorotynsky for their numerous merits. By 1746, the village and the surrounding wastelands were part of the Mosalsk district and belonged to Major Dementy Kamynin. By the end of the 18th century, the owners of Lyubun and three neighboring villages became landowners Ivan Nemirov, the Mokeyev sisters, Stepan Kaporsky, Domna Sukhodolskaya, and Vasily Yakovlev. According to archival documents, at that time, the estate included a wooden manor house with a garden and the wooden Assumption Church.

In 1782, Colonel Nikolai Protopopov, a landowner in the surrounding villages, acquired part of the estate's lands and serfs, but the main owner of Lyubun became the Mosalsk landowner, second-major Anton Klyustin. After moving to Lyubun, Klyustin invested significant funds in the construction of a stone church of the Assumption of the Blessed Virgin Mary, which replaced the wooden church and surpassed all the churches in the district in grandeur and decoration. The church, covered with iron and surrounded by a metal fence with towers, was adjacent to a stone bell tower.

The noble estate was located on an elevated site and was surrounded by necessary services. A one-story stone house with a central entrance and a three-windowed mezzanine was approached by linden and birch alleys. Around the house was a well-kept garden with various fruit trees, and wooden bridges known as the Blue and Punakin bridges spanned the Kamenez River.

In the late 19th century, the estate was acquired by merchants Nil and Ivan Domany, owners of a large matting factory. At that time, there were three forges, a zemstvo school, and a small sawmill owned by entrepreneur M. Ananyev, employing 20 people. Three years before the revolution, a two-story hospital was built on the outskirts of the village, part of which housed a church parish school. It competed with a ministerial school for capable peasant children from nearby villages. Near the Assumption Church, surrounded by a garden, there was a hospital where a feldsher lived. Services in the old church were conducted by two priests with the help of a deacon, psalmists, and a bell ringer until 1929, after which the church was closed, looted, and dismantled for bricks. A memorial cross now stands in its place.

The main manor house was used for some time by the poverty committee and the village council, and after the Great Patriotic War, when only two houses remained in Lyubun, a rural school was opened there. The building is now vacant.
