The Amasya Museum houses two collections worth your time. The ethnographic section occupies a beautifully restored Ottoman building and covers the domestic life, costumes, and crafts of the region across several centuries. It is the kind of collection that most provincial Turkish museums do well, and this is a good example.
The centrepiece, however, is the mummy room. Seven naturally preserved corpses from the 13th–14th century Mongol Ilkhanate period are displayed here, their faces weathered but remarkably intact. They were found beneath a mosque in the city in the 1930s and have been here ever since. The display is matter-of-fact rather than sensationalist, and the informational context provided is genuinely useful. Allow an hour for both buildings.
