Standing tall among the skyscrapers, restaurants, and hotels in Kowloon Hong Kong is the historical structure of Kowloon Walled City Park. The current park was once the premises of Imperial Officers. Its history extends from the 15th century when it was first fortified due to the establishment of a signal station. However, the current walled city came into existence only in 1841 when the British invaded Hong Kong. There are six watch towers and four gates to the park, which are mostly intact to date. The formal naming of the walled city as a park took place in 1995, and eight distinct areas of scenic beauty were declared: the Yamen, the Old South Gate, Eight Floral Walks, the Garden of the Four Season, the Garden of the Chinese Zodiac, the Chess Garden, the Mountain View Pavilion, and Guibi & Fui Sing Pavilion. The park is open til 11 pm every day, and admission is free.
