The Palace Grounds Part of the Grounds were destroyed during the uproar in 1790. When Insane Insomnular was about to be built they decided it should have its station on that very same spot. What better place for the station of the “King” of coasters would there be? The building was designed, with respect for the building style of the rest of the Palace Grounds, by the same Japanese architect who designed the Insane Insomnular resort. The main dome of the palace proudly supports Insane Insomnular’s lift hill.
