The Five Corners was a premium, limited time decoration released on May 5, 2015 during the Terwilligers 2015 Event.
It returned on February 27, 2019 during the State of Despair 2019 Event.
Five Corners is the only place in the US where five states meet. It does not exist anywhere in the United States of America. It is most likely based on the real USA attraction, the Four Corners, which contains Utah, Colorado, Arizona, and New Mexico.
