Tsiolkovsky built a custom-designed ear trumpet in this house to cope with the severe hearing loss he suffered since childhood.
The house narrowly survived the destruction of the 1941 occupation of Kaluga when the building was damaged but not demolished.
Tsiolkovsky utilized the attic of this house as a primary observation deck for his astronomical studies.
The scientist's original bicycle, which he used to commute through Kaluga, is displayed on the property.
The museum interior retains the original wall color and furniture arrangements noted in family photographs from the early 20th century.
The Memorial House-Museum of K. E. Tsiolkovsky in Kaluga is the preserved residence where the father of theoretical astronautics lived and worked for 29 years. Tsiolkovsky moved into this wooden house in 1904 and remained here until 1933, creating his foundational works on rocket science and space flight theory. The museum preserves the authentic interior, including the scientist's study, workshop, and living quarters exactly as they appeared during his lifetime. Visitors can view his original telescope, ear trumpets, and handmade models. The museum is a branch of the State Museum of the History of Cosmonautics. It is situated on the banks of the Oka River, near the area where Tsiolkovsky frequently took walks to observe the sky.

Visit the larger State Museum of the History of Cosmonautics nearby for a comprehensive view of the rockets the scientist theorized.
Check the museum's official website for temporary exhibitions on local Kaluga history that occasionally supplement the permanent collection.
Take time to explore the small, well-maintained garden surrounding the house, which recreates the atmosphere of Tsiolkovsky’s era.
Do not confuse this house museum with the larger, main aerospace museum nearby; they are separate buildings with different displays.
