Gunwharf Quays will step back in time for the Policing Through The Ages event.
Families will be able to see a display of more than 70 classic service vehicles and some of the equipment police officers have used over the past 80 years.
The free event on Saturday, October 3, from 10am will also feature cars from classic TV shows Starsky & Hutch and Dukes of Hazzard.
Members of Hampshire Constabulary’s marine unit and dog unit will be on hand to demonstrate how their work has changed since the 1940s.
Children will have the chance to play detective on a trail around the centre and the whole family can enjoy entertainment from the Hampshire Police Band and Choir throughout the day.
