Shek Lung Kun Beacon (石攏拱墩臺) - Undocumented [????- ]
I am including this as a curiosity. This thing has every characteristics of other beacons mentioned, but it was undocumented in any municiple or county gazzet. So It has direct line of sight with Beacon Hill Becon, and clear visibility of our Western Harbour.
It is just beside the Yuen Chuen Ancial Trial, very easy to visit. But you would have to know where to look in order to locate it. There are a few mud/rocky paths leading to its vicinity, but directly to its location. Nature had been reclaiming this site. The beacon is now covered with grass with a small tree standing in the depression in the middle of it. But if you are there, you should be able to see it is an artificial structure. Give it a few more years, this beacon would be obscured by the trees around it from all sides.
