THAMES Valley Police has a museum based in Suhampstead that is open to visitors on Wednesdays.
The interactive exhibition features displays on the history of the force, and the five police forces that merged to form it, including Berkshire.
There are special displays dedicated to some of its biggest cases, including the Great Train Robbery of 1963, and the Denham Murders of 1870.
Also on show are collections of police uniform and equipment.
Using smartphones and headphones, visitors can make use of the interactive dispalys.
It is open from 10am to noon each week. As it is based in a police base at Sulshamstead House, visitors need to be accompanied.
