This enormous park was built in the early 15th century, around the same time the Forbidden City was constructed. The park hosts several intriguing buildings. In the north of the park, a stone carved stairway leads up to the entrance of the Hall of Prayer for Good Harvests with its cylindrical blue-tiled roof and a beautifully decorated ceiling. It was struck by lightning and burnt to the ground in 1889 but was carefully reconstructed the following year. The Hall of Abstinence was used by emperors for fasting. In the south, you will find the Round Altar—a three-tiered marble platform.

Aya Sofya is a remarkable mixture of Christianity and Islam, a church with minarets and a mosque with pictures of the Virgin Mary that, unfortunately, are now covered up. The building is one of the wonders of world architecture. Its 32-metre main dome has stood firm since Aya Sofya's completion in 537 CE. That's almost one and a half thousand years ago. Originally constructed as a Christian church, the temple has since been a mosque, then a museum, and now once again acts as a mosque.
