The first time I went to the Warner Brothers Harry Potter Studio Tour was in 2015, just after they had added the Hogwarts Express and Kings Cross set to the tour. At the end of November 2019 we made a return visit, mainly to see how different it was dressed for Christmas and with snow.
The Gryffindor dorm and common room were dressed for Christmas with a tree, decorations and presents.
Gryffindor is one of the four Houses of Hogwarts School of Witchcraft and Wizardry and was founded by Godric Gryffindor. Gryffindor instructed the Sorting Hat to choose students possessing characteristics he most valued, such as courage, chivalry, and determination, to be sorted into his house. The emblematic animal is a lion, and its colours are scarlet and gold.
