More than 40 visitors toured the Bunker - a basement museum at Hatfield Police Station.
The free, public museum looks at the history of the Grade II listed building - a former aircraft factory - and now serves as a key site for fostering community relations, as well as celebrating the location's heritage.
The museum showcases various photographs, historical artefacts, original film footage, models, and dioramas.
Forty-six people attended the open day on Saturday, April 20, many of whom held personal connections to the De Havilland aircraft factory, which was once based in the building.
PCSO Anne Devine, from the Neighbourhood Policing Team, along with police support volunteer Alistair Hodgson, gave a tour to the guests.
As well as offering insight into The Bunker's history, they also gave attendees the opportunity to raise any issues with crime in their area.
PCSO Devine said: "It was an extremely busy day for us in the Bunker but it was all worth it to see the smiles on everyone’s faces!
"It’s great to see that the public are so enthusiastic and we can’t wait to keep showing more people around."
“We heard lots of fantastic stories from attendees who had personal connections to the Bunker.
"A lot of them had family members who had worked at the De Havilland aircraft factory. It was a privilege to give them the opportunity to step back in time and relive treasured memories.
"One of our rooms in The Bunker explains the history of policing and it’s always a pleasure to speak to residents about this.
"We then explain the world of modern policing and it presents an opportunity for residents to raise any thoughts or concerns about local policing in Welwyn Hatfield."

Community voice platform, ‘echo’, can also be used to give feedback and help shape local policing priorities.
The next open day, scheduled for May, is already fully booked, with more to be announced in due course.
