The Alexander Grin Museum in Feodosia is located on Gallery Street in the house where the writer lived and worked from 1924 to 1929. Since the mid-1970s, it has operated as a memorial-literary museum, initially overseen by the Feodosia Local History Museum. The museum's design was created by artist-architect S. G. Brodsky. The building is easily recognizable by the large romantic relief panel "Brigantine" that adorns its end.

The permanent exhibition includes a recreated writer's study with an emphasis on everyday details, as well as rooms decorated in the style of Grin's romantic world: "Hold of the Frigate," "Clipper Room," "Cabin of Wanderings," and others. The large hall features the exhibition "Grin and Modernity." The museum also hosts temporary thematic exhibitions and meetings with musicians, poets, and artists.

The image of the museum resembles an ancient sailing ship, and its atmosphere is infused with the writer's creativity and the romance of sea voyages, evoking memories of childhood dreams. The Grin Museum in Feodosia differs from typical academic museums in that it focuses not on the writer's biography but on the world of his works and characters. The exhibition is permeated with the spirit of romantic creativity.

The small one-story building, which was Grin's home, is designed as a symbolic sailing ship, except for the memorial study-room. The white walls are lined with dark wood and decorated with marine knots made of sisal rope. The rooms resemble holds and cabins, with names like "Grinlandia," "Hold of the Frigate," "Cabin of Wanderings," "Clipper Room," "Rostral Room," and "Captain's Cabin."

The exhibition includes not only photographs and manuscripts but also models of sailing ships, antique navigational instruments, maps, and lighthouse lanterns. At the entrance, visitors are greeted by a "Rose of Winds" and a panel map of the fantastic land of Grinlandia, created by the writer.

The "Hold of the Frigate" room is dedicated to maritime romance, the main theme of Grin's work. The walls are covered with stays made of sisal rope, and the lighting is created by ship lanterns. The "Cabin of Wanderings" is dedicated to Grin's childhood and youth, combining documentary elements with romantic elevation. Here, one can see a model of a clipper, the first sailing ship in the writer's works.

In the "Clipper Room," the ceiling is adorned with a ship's hatch, and the windows have gridded shutters and carved zodiac signs. The "Rostral Room" is named after the rostra, the bow of a ship, creating the impression that the ship is sailing into the room. Here is a model of a ship with scarlet sails, attracting the attention of many visitors.

This room recreates the atmosphere of a captain's cabin with antique chairs, a table decorated with inlay, and other nautical attributes. It is here that the novel "Running on the Waves" was written, where the theme of the sea resonates particularly strongly due to Grin's move to Feodosia.
