More than 150 people had the chance to see archaeology in progress during a dig that was open to the public at Watford’s Cassiobury Park.

The event on Saturday followed two weeks of excavation at the site of the demolished Georgian Swiss Cottage. The Swiss cottage and grounds were used for picnics and parties for the Earl of Essex’s family and friends.

People were able to talk to archaeologists, see the uncovered artefacts and learn more about the historic site during the open day, which was organised by SW Herts Archaeological and Historical Society and Watford Borough Council.

Other attractions included tours of the trenches that were dug during the excavation, an art exhibition and various family activities.

Elected Mayor of Watford, Dorothy Thornhill, said: “It was great to see so many people enjoying a trip to the park while learning about the history of our wonderful town.

“Our archaeologist was so busy he could only take a half-hour break.

“We had lots of families, and children as young as four taking part.”
