The Cater Museum houses many artifacts of Billericay and contains a lot of local information.
The 18th to 19th century red brick building is tiled and has dormer windows, one of which depicts the war time practice of applying tape to reduce flying glass. The centre window of the first floor is bricked up - this is a reminder of the window tax. Within the three floor building you will find a mid Victorian parlour, bedroom and kitchen, as well as a World War II exhibition.
The garden behind the museum is being restored to a period kitchen and herb garden.
