One of the largest Ocean Discovery Parks in Europe, the Océanopolis has four pavilions — polar, temperate, tropical and biodiversity — that tell the story of the sea and marine life in different world climates. The park contains an impressive 7 shark species.

First opened in 1981 within the Confucian Temple, the Capital Museum relocated to a purpose-built modern building in 2006 to accommodate its growing collection. It holds over 200,000 cultural relics; approximately 5,000 are typically on display at any given time, featuring a diverse range of items including porcelain, jade, calligraphy, paintings, coins, and Buddhist statues.

Built in the early 1400s, around the same time as the Forbidden City, the Temple of Heaven was where emperors prayed for good harvests. The vast park contains several ceremonial buildings, the most striking being the Hall of Prayer for Good Harvests with its blue-tiled roof and intricate wooden ceiling. The original hall was destroyed by lightning in 1889 but rebuilt soon after. Other highlights include the Hall of Abstinence, where emperors fasted before rituals, and the Circular Mound Altar — a three-tiered marble platform symbolising heaven itself. Today, the park is as much about everyday life as it is about history: locals gather here in the mornings for tai chi, dancing, and music.
