Which town hosts the world's largest sculpture park made by a single artist?

Frogner Park is the largest park in the city and covers 45 hectares; the sculpture installation is the world's largest sculpture park made by a single artist. Frogner Park is the most popular tourist attraction in Norway, with between 1 and 2 million visitors each year, and is open to the public at all times.
