This small literary museum is tied to Anastasia Tsvetaeva, who lived in Alexandrov during the First World War, and to her sister Marina, one of Russia's great poets. It is not a large museum, and the visit depends heavily on guided interpretation, but the story is worth hearing if you care about Russian literature.
The museum also touches on Alexandrov's role as part of the Soviet "101st kilometre" world, where people barred from Moscow were pushed just beyond the capital's permitted radius. That gives the town a 20th-century layer beyond its Ivan the Terrible story.
