The Tung Chung Fort is part of a collection of historic attractions that make up the Relics of Tung Chung, as sponsored by the Hong Kong Antiquities and Monuments Office (AMO), while not a formal heritage trail, there is a pamphlet with map and description of the various historic attractions including the Tung Chung Fort on their website for those interested.
This is historic Qing Dynasty Fort is a Declared Monument in HK. It was constructed in the early 19th-century for the purpose of defending the coastal lands around modern day Tung Chung on Lantau Island. It is located on the south side of Tung Chung Road and can be conveniently visited along with the other Relics around Tung Chung including the Tin Hau Temple, Hau Wong Temple, Tung Chung Battery and Fu Tei Wan Lime Kiln
What you will find is a restored fort wall which you can climb and walk all the way around. The front includes six mounted cannons from the 19th century, although it is not known if these were originally from this particular fort. There is a small Centre inside the fort walls with information and artefacts for this and other of Relic historic attractions mentioned above. The Centre is open from 10am to 5pm (Wed - Sun) but closed on Tuesdays.
The fort was occupied and in use throughout the 19th-century but was abandoned in 1898 when the New Territories was leased to the British. It was then used as an early police station by the British and later as by Wa Ying College, Rural Committee Office and lastly a public Primary School in Tung Chung, for which you will find old abandoned school buildings within the fort grounds.
Overall, the restored fort is an interesting historic place worth finding if you plan to spend time in the Tung Chung area and have interest in such sightseeing. It also makes for a fairly convenient detour attraction to visit for those planning on doing the Ngong Ping 360 Rescue Trail or the Tung O Ancient Trail, it is not far out of the way of these trails if you have the time and energy.
