About The Festival
The King John Summer Prom festival was a massive success in 2025. We saw great movie scores with a live Orchestra on the Friday Evening followed by a Saturday matinee with the Movie scores of the Legend James Horner been played by one of Ireland’s leading Orchestras. We then played a live screening of the Braveheart movie with Mel Gibson in the audience as a special guest along with a variety of other cast members and members of the William Wallis society from Scotland. Then on Sunday the festival was closed out with a concert, the Neill Diamond Hot August night show.
The festival returns this year in July 2026 to a new location – the Trim Castle Hotel. This indoor venue is located in the middle of Trim town with easy access to shops, pubs, hotels and public transport. Full information on the event for 2026 is detailed below.
