Thousands of visitors are expected to descend on Waunfawr Park in Crosskeys for Armed Forces Day celebrations.
The event will be held on Saturday, June 22 and Sunday, June 23.
The family-focused event is held each year to celebrate the work and contribution of armed forces personnel to the community.
Waunfawr Park is expected to host up to 200 stalls, selling crafts, trade goods, artisan food and drink and more.
A funfair will be running from 9am to 5pm on both days.
There will also be a range of military-themed activities suitable for all ages, such as an army night vision maze, bungee trampolines and military re-enactments, and visitors will be able to see both modern and vintage military machinery up close.
A variety of live music will also be on offer, with performers including the Band of the Royal Welsh, Cardiff Military Wives Choir, vocalists and cadet bands performing over the weekend.
Meanwhile, a 1940s-themed concert will be held in the entertainment marquee from 6pm to 11pm on the Saturday, with tickets priced at £12.50.
To buy a ticket for the concert, contact Tim Sturges on 07811 016335 or email friendsrblbandofwales@gmail.com.
The official flag raising ceremony will be held on the Sunday at 11am.
The Armed Forces Day celebrations are held each year and are organised by the Royal British Legion and Caerphilly County Borough Council.
The event is held to raise money for the Royal British Legion Band of Wales.
The celebrations will be free to enter, but voluntary donations can be made to the Royal British Legion during the event.
Last year’s event, which was also held in Crosskeys, attracted more than 7,000 visitors.
