After the death of Sergey Alexandrovich Yesenin in Konstantinovo, his admirers often reached his home on foot. The poet's mother, Tatyana Fedorovna, and later his sisters Alexandra and Ekaterina welcomed numerous visitors at the Yesenin house. Thousands of entries with wishes to open a museum dedicated to the poet in Konstantinovo were left in the guestbooks. On July 28, 1965, a decision was made to immortalize Yesenin's memory in his homeland. The memorial house-museum, opened on October 2, 1965, as part of the Ryazan Regional Local History Museum, eventually became one of the largest museum complexes in the country. The central object of the museum-reserve remains the house of Sergey Yesenin's parents. The exhibition transports visitors to the 1920s when the poet visited his relatives in Konstantinovo. In the house, one can see household items and peasant utensils. By the window in the hallway stands a wooden bed with a patchwork quilt, next to it a chest with books of Yesenin's favorite writers. In the room, family photographs and a certificate of merit received by the poet upon graduating from the zemstvo school hang on the wall. In the poet's mother's room, one can see her clothing and the famous 'shushun' mentioned in Yesenin's poems. Interest in the museum grew, and in October 1969, a literary exhibition opened in the estate house of L. I. Kashina, detailing the life and work of the poet. In September 1970, the memorial house-museum was renamed the Literary-Memorial Museum of S. A. Yesenin. In the 1980s, new museum exhibitions appeared, including the Church of the Kazan Icon of the Mother of God, which became part of the museum in 1972. In 1990, the church was returned to the Russian Orthodox Church and became active. In 1984, a decision was made to create the State Museum-Reserve of S. A. Yesenin based on the existing museum and memorial sites in Spas-Klepiki. The literary exhibition of 1995 features unique exhibits, including lifetime editions of the poet, a book 'Radunitsa' with an autograph, the desk at which Yesenin worked, his death mask, and personal belongings. A new exhibition in the Spas-Klepiki school tells about the humanistic traditions of Russian teaching and the formation of the poet's creative personality. In 2010, a new exhibition was opened next to the church in the house of priest I. Ya. Smirnov, which was a cultural center of Konstantinovo in the early 20th century. In recent years, the museum's collections have been enriched by the collections of Yesenin scholar Yuri Prokushov and literary scholar Gordon McVey. In 2019, a unique collection of 124 glass stereoslides from the 1900s, belonging to the descendants of Lydia Kashina's family, was acquired, which will help restore the lost buildings of the estate.
