Police officers from Hertfordshire Constabulary visited the 'Becoming Us' exhibition at St Albans Museum + Gallery as part of the force’s work to become an anti-racist service.
The exhibition was attended by ranks varying from police constable to assistant chief constable, on June 27.
Co-curator Andrene McDonald, from the voluntary organisation Active Lifestyles, hosted the officers.
She is also a member of the constabulary’s Race Inclusion Board, which provides the force with advice on tackling "racial disparities in policing".
The display, which shone a light on the lives of people from the Windrush generation, has been on since February, with its closing day on June 30.
It attracted more than 26,000 visitors.
Assistant chief constable Catherine Akehurst said: "We are committed to being a service that actively challenges discrimination wherever it is found and builds trust and confidence in policing among our black communities.
"This visit was a small part of this work but shows our commitment to understanding and learning from the past to better understand the present.
"We want to learn about black history and hear from our black residents, listening and positively engaging with them.
"By doing this, we can hopefully better respond to the needs and the issues affecting our communities today.”
