Millgate Museum is in Newark, Nottinghamshire. It is housed in a Victorian warehouse on the banks of the River Trent. It opened in 1976 and is part of the Millgate Conservation Area, an area of great historical and architectural interest. The displays are spread over three floors and cover the agricultural, industrial and social history of Newark. The upper levels are accessed only by stairs. There is a cafe on the ground floor serving light refreshments, with a view of boats passing on the river.

The Museum has fun educational activities for children and fascinating exhibitions including streets, shops and rooms in period settings. It has various items from archaeology, natural history, costume and art, to photographs, social history, civil war and military items. A small selection of objects from all of these areas are on display at the Museum in permanent and temporary exhibitions.

The Mezzanine Gallery within the museum is a venue for temporary exhibitions featuring the work of local artists, designers and photographers and provides members of the public with the opportunity to purchase unique artwork. Millgate Museum also operates a fine Research Service and provides local people with the chance to get involved with museum work via the Friends and Volunteer Groups.
