The Munot is a circular 16th century fortification in the center of the Swiss city of Schaffhausen. It is surrounded by vineyards and serves as the city's symbol. The ring-shaped fortress was built in the 16th century. Today, it is a tourist attraction and hosts various events.

Earliest presence of a castle dates to 1379.

The current complex was built between 1564 and 1589 under the city master builder Heinrich Schwarz (1526–1593), probably to the knowledge of Albrecht Dürer's work of a circular fortification.

It is one of the few examples of the transition from a castle to a modern Fortress. The Munot was part of the city fortifications. The construction cost the city 47,528 guilders, which corresponded to the construction costs of around 800 townhouses.
