The marker is marked based on the GPS coordinates of the Trigoman's Castle Peak 517m Trigo Station. If there are errors they are entirely mine. Thanks should be made to JW and his gang for the location and theory of this site, together with the Shek Lung Kung site.
The location is documented in 新安縣誌﹐ and some other documents. The discussions of JW and his gang concerning this Beacon and others could be located here. The discussions are generally in Chinese.
