The black background indicates Fareham's strong association with industry.
The ship of gold represents the town's ancient prosperity as a port and shipbuilding centre. The chief shows the arms of the See of Winchester, recalling that Fareham was in the past part of the endowment of the See and was formerly part of the diocese of Winchester.
The keys and sword refer to the parish church of SS Peter and Paul.
On either side of the keys is a red rose which is the chief emblem of Hampshire and symbolises the county's former Lancastrian association. The motto is in French and, roughly translated, means 'Ready to act'.
