Final answer:
The original Hobbiton set was built in 1999, just before the year 2000, for 'The Lord of the Rings' trilogy.
Step-by-step explanation:
The original Hobbiton movie set was built in 1999 for the filming of Peter Jackson’s “The Lord of the Rings” trilogy. This places the construction shortly before option b) 2000. The set was constructed on a family farm near the town of Matamata, in the Waikato region of New Zealand. It was designed by production designer Grant Major and built by the New Zealand Army. The set was initially intended to be temporary, but after the success of the movies, it was rebuilt for “The Hobbit” movies and now serves as a permanent tourist attraction.
