Kapuvár is a small but ancient town of some 11,000 inhabitants in Győr-Moson-Sopron county, Hungary. The town is known for its thermal water which some believe has hydrotherapeutic properties. It is served by highway 85, and has a train station. It borders the Fertő-Hanság National Park, 15 kilometres from the border station of Pomogy. The settlement was fortified as early as the 11th century and was the estate owned by the Nádasdy family in the 16th century. St. Ann's church contains an ancient cemetery that is still being used.
