Queen Elizabeth II and Prince Philip visited the set of HBO’s Game of Thrones while touring Paint Hall Studios in Belfast, Northern Ireland’s Titanic Quarter recently.

The duo toured the set, checking out many of the show’s elaborate set designs, props (including that awkward moment when you have to tell the Duke of Edinburgh he’s holding a castration knife [31:40]), and costumes, and met with various cast and crew, including showrunners D.B. Weiss and David Benioff and stars Maisie Williams (Arya Stark), Sophie Turner (Sansa Stark), Rose Leslie (Ygritte), Kit Harington (Jon Snow), and Lena Headey (Cersei Lannister).
