The year is 2024. The world has been almost destroyed by fire-breathing dragons and the last surviving humans live in a castle in a remote part of England.

One of the main sets for Reign of Fire was a huge modern castle/fort that was built in the middle of the Wicklow Mountains, on top of some old lead mines. This is a very sensitive location, in the middle of the Wicklow Mountains National Park, and thus it was important to cover the site with a membrane before work commenced in order to facilitate the restoration of the site after filming was finished. Many of the aerial shots were taken over the Sally Gap and Wicklow Mountains. Ballinascorney Quarry near Blessington was also transformed for the film into a blackened looking waste ground with some vegetable patches. The Black Castle ruin and surrounding grounds, in Wicklow Town, were used as a graveyard. Ardmore studios hosted this film and it’s production offices.
