Time Out says
Built during the Ming Dynasty, Kat Hing Wai has been the settlement for the indigenous Tang Clan since the 15th century. Now rated as a Grade I historic building, the compound allows you to literally step back in time to Hong Kong’s rich history. The walled village was originally built with a moat as a defence against British rule in 1899 where the Iron Gate stood strong between the British and the natives. The British, however, eventually broke through and the Iron Gate was torn down and shipped to England. It was not until 1925 when the British Hong Kong government managed to retake ownership for the piqued descendants and resurrect the Iron Gate into a monument.
