There are no museums in Fyvie, except for Fyvie Castle itself which to my mind is greater then any museum.  Nearest museums are the Auld Post office Museum Turriff, the Session Cottage Turriff about 5 miles north.  Banff museum about 20 miles north.  Inverurie museum about 10 miles south west.  Fraserburgh Heritage centre and the Scottish Lighthouse Museum Fraserburgh about 25 miles north east.  Arbuthnott museum Peterhead about 20 miles east.  Or the many museums in Aberdeen about 20 miles south.
