In her blog article, Rachel describes working on the production, from watching the behind-the-scenes magic to working on different locations in both France and Wales.

Though the castle used for the mythological Camelot is Château De Pierrefonds, situated on the southeast edge of the Forest of Compiègne, north of Paris, there are many Welsh locations used in the filming of each series. As Rachel says:
"We're fortunate that there are so many fantastic locations on our doorstep. From the ruins of Neath Abbey, to the wilds of Trefil, Merlin just wouldn't be the same without them.
"They need to be pretty spectacular to stand up to the Château, but I'd say they more than hold their own."
