Throughout the century-long history of the estate, many events have taken place here, making it not only an architectural but also a historical and cultural landmark of regional significance. The main building of the estate, the Obninsky House, was constructed at the turn of the 19th and 20th centuries by V.P. Obninsky. Architect V.M. Lopatkin designed it in the style of neo-English modernism. A distinctive feature of the building was the eight-meter tower, which Obninsky used as an observatory.

In 1909, the estate was acquired by the widow of Moscow manufacturer M.A. Morozov, Margarita Kirillovna Morozova. She named it "Mikhailovsky" in honor of her husband or, according to another version, her son Miki. However, another name became established, "Morozova's Dacha" or "Morozovo." At her request, the building was reconstructed by the famous Moscow architect Lev Kekushev. A wooden guest house and a manager's house were built. Both under the Obninskys and the Morozovs, the estate hosted many representatives of the creative intelligentsia, including artists and musicians.

After the 1917 revolution, the building came under the management of S.T. Shatsky's school-colony "Cheerful Life." Lessons were held for students and pedagogical courses for teachers from nearby villages. Before the war, the building was used as a dormitory.

During the war, the Germans occupied the building, and after the counteroffensive of the Soviet army, the estate housed the command post of the Western Front headquarters, led by three commanders, including G.K. Zhukov. At that time, the building lost its tower to avoid attracting aerial attention. The surrounding area and the building itself were camouflaged with nets. Numerous communication and evacuation tunnels, known as "Zhukov's Caves," were dug at that time. In peacetime, the tunnels were blocked due to safety concerns for teenagers.

After the war, the building housed a hotel for the secret "Laboratory B" and a health resort, which later became part of the Physical Energy Institute. In 1949, the building was reconstructed and restored, combining modernism and "Stalinist Empire" styles.

Today, Morozov's Dacha is the oldest stone building in the young city of Obninsk. In the fall of 2015, the building and the estate's territory were transferred from the Physical Energy Institute to the municipal ownership of the city and are under round-the-clock protection. The estate is managed by the Obninsk City History Museum. Conservation work has been completed, and further restoration is planned.
