Sun Shrine

Sun Shrine is a location in  that appears in 2300 AD. It appears in its original form in the Antiquity, although it is not accessible. The Son of the Sun resides inside.

Story
The Sun Shrine is an ornate structure designed by the people of Zeal to house the Sun Stone, which was used prior to the advent of the Mammon Machine as their primary energy source. The palace floated west of the other islands, and was sealed up after the Mammon Machine was created. It sunk to the bottom of the ocean after the collapse of Zeal, where it remained until mysteriously appearing in the ruined future. Crono acquired the Moon Stone there after defeating the palace's formidable guardian.

Trivia
The Sun Shrine is referred to as the "Sun Keep of Zeal", causing much confusion. That the Sun Keep and Palace both exist in the ruined future is proof that they are different structures.
