Fantasy: Forbidden City
The ancient city was constructed in the early 15th century and was the former Chinese imperial palace and winter residence from the Ming Dynasty to the end of the Qing Dynasty. Since 1925, the Forbidden City has been a museum rather than a working palace.
The complex consists of 980 buildings and 9,999 rooms. They should build another room somewhere just to pacify those with OCD. It receives an average of 14 million visitors annually.
