Cornerstone Hill

Cornerstone Hill is a place in Kingdom Hearts II. It appears in Timeless River.

Cornerstone Hill is the area where the Cornerstone of Light was held during the construction of Disney Castle many years ago. The Cornerstone was placed on a large pedestal in its center.

In the game, the three classic Disney characters Clarabelle Cow, Horace Horsecollar and Clara Cluck could be always be seen wandering around Cornerstone Hill.

Cornerstone Hill is also home to the entrances to the four Windows to the Past of Timeless River: Lilliput, Building Site, Mickey's House and Scene of the Fire.

Meanwhile during the events of Sora, Donald, and Goofy, a few cut scenes are shown telling that the door that the trio is looking for is found by the present-day Pete. It also leads to Cornerstone Hill. Maleficent gives orders to Pete to take the Cornerstone and destroy it so that the light of the future Disney Castle can never be restored. But with the help of the past Pete, Sora, Donald, and Goofy defeat Pete.

This is where Sora comes out of the other side of the door that Merlin made in Disney Castle.
