Beacon - Tai Po Tau 大步頭墩台 (according to 新安縣誌), early Qing. [????- ]
Location is just a speculation. It is based upon a present day village called Ying Pun Ha (營盤下)。Ying Pun (營盤) means a military camp and Ha (下) means under/below. The name of the village literally means "the village below the military camp' in English. If the beacon was there it would be somewhere along the ridge.
