This is my homemade 1:186 Hogwarts grounds model.
It includes: Hogwarts castle, stone circle, the owlery, quidditch pitch, whoomping willow, Hagrid's hut, and parts of the black lake and forbidden forest. This model is based on the Hogwarts we see in "Goblet of Fire" and "Order of the Phoenix".
It took me 3 months to make it (3 weeks for the blueprints only).
Hope you like it
