Pembrey Country Park will travel back in time to World War I over the May bank holiday.
Thousands of visitors are expected to turn out to see infantry, cavalry, medical services, munitionettes, period police officers and civilians from that era interacting with each other.
A WWI field hospital will be staged, complete with medical equipment.
The two-day event on Sunday and Monday, May 6 and 7 promises to be bigger and better than last year and gives visitors an insight into what it was like living during that period.
Visitors will also be able to meet the Yeomanry and their mounts, be instructed on the use of arms and equipment and learn about the shady activities of the members of ‘La Dame Blanche’ (The White Lady).
A mix of living history and talks will be delivered by historians, experts and authors on the fighting at Mametz and the engineering projects built by conscientious objectors as well as the general history of Pembrey munitions factory.
Dyfed Archaelogical Trust will also be there to provide information on the history of the park.
Entry to the event is free. Usual car parking charges apply.
