Tsiolkovsky memorial house, Space pioneer memorial house in Kaluga, Russia.
Tsiolkovsky's memorial house is a wooden residential building with two floors located in Kaluga. Inside, the rooms where the scientist lived remain preserved, along with his study and workshop where he developed his ideas about space travel.
Tsiolkovsky bought the house in early 1904, when it was a single-storey building with one living room on the town's outskirts. After the 1908 Oka flood damaged it, he had it repaired and enlarged with a second floor housing his study and a veranda workshop. He lived here until 1933, then moved to a house given by the city council for his 75th birthday. The museum opened on 19 September 1936, a year after his death.
The house displays items from Tsiolkovsky's daily life and work that show his role as a space travel theorist. Visitors can walk through his personal rooms and understand how he worked and lived in his everyday surroundings.
The house is open to visitors on several days each week, with longer opening hours on certain weekdays. It is helpful to check the exact times before visiting, as they may vary depending on the season or special events.
In the museum courtyard stands a small bronze figure of a boy in a cradle, called Cosmonautics No. 001, donated by its sculptor Alina Farnieva. The 1908 flood damaged the house, but the scientist's papers were not lost then; the museum's exhibits were destroyed during the Nazi occupation in 1941.
