The memorial house-museum of A. S. Grin is dedicated to the writer Alexander Grin and is the oldest museum in Old Crimea, founded in 1960. It is the first museum dedicated to Grin, and since 2001, it has been part of the Koktebel Eco-Historical and Cultural Reserve "Kimmeria of M. A. Voloshin."

The uniqueness of the museum lies in the fact that it is located in the only house that belonged to the writer himself. The house was purchased in May 1932 by Grin's wife, Nina Nikolaevna, in exchange for a gold wristwatch and became the writer's fourth address in Old Crimea. It was here that Grin spent the last days of his life, dictating pages of the unfinished novel "The Touch-Me-Not" and receiving the last lifetime edition of "Autobiographical Story."

The museum's exhibition consists of three small rooms. The first room features the writer's personal belongings, photographs, books, and paintings that tell about his life and work in 1929 and 1932, related to Old Crimea. The second room recreates the atmosphere of Grin's last days, with the only change being the wooden floor, as the floor was earthen during the writer's lifetime.

The museum was created thanks to the efforts of Nina Nikolaevna Grin, who, despite the difficult years of German occupation and subsequent trials, did not abandon her dream of creating a house-museum in Old Crimea. After Stalin's death, when the ban on Grin's work was lifted, his works began to be published en masse. Nina Nikolaevna, receiving a fee for "Selected Works," returned to Old Crimea, where she found that Grin's house had been used as a shed and chicken coop.

In 1960, after long efforts, Nina Nikolaevna opened the museum on a public basis. The memorial room was opened in May, and on August 23, the day of Grin's eightieth birthday, the museum was solemnly inaugurated. In 1964, the museum became a branch of the local history museum of Feodosia.

Nina Grin spent the last ten years of her life in this house, living on a pension of 21 rubles. After her death in 1970, the museum and its collection were transferred to the state. In 1971, the museum became state-owned, despite the conflict with Nina Nikolaevna, and became a branch of the Feodosia Literary and Memorial Museum of A. S. Grin.

Since 1996, the museum has been part of the Literary and Artistic Museum of Old Crimea and is a part of the "Kimmeria of M. A. Voloshin" reserve. Since 2015, it has become a department of the Literary and Artistic Museum, a branch of the State Budget Institution of the Republic of Crimea.

Every year, in honor of the writer's birthday, the "Grinlandia" festival takes place in Old Crimea from August 22 to 24. Festival participants raise scarlet sails on the slope of Mount Agar-Mish, and creative groups, artists, and poets perform on stage. The festival includes exhibitions and excursions, and on August 24, participants make a hike from Old Crimea to Koktebel, retracing the route taken by Grin in 1931.
