Store norske leksikon writes that "At søndre Låke gård (a farm), South of Nannestad Church, Skule Bårdsson beat Birkebeinar (a political group), [... on a battlefield] South of the farm".

[4] The municipality (originally the parish) is named after the old Nannestad farm (Old Norse: Nannastaðir), since the first church was built here.

The arms show three yellow coltsfoot flowers on a green background.

[5] Nannestad is located in northwestern Akershus county, with inhabitants concentrated at Romerikssletta.

It includes the villages of Maura, Åsgreina, Eltonåsen, Steinsgård and Teigebyen, that last being the administrative centre.
