Kun Lung Wai, presently known as San Wai, is one of the eleven Tang villages in Lung Yeuk Tau, Fanling. Although this village was reportedly settled by members of the Tang clan during the 14th century, the walls of San Wai were believed built in 1744 as the stone lintel above the main entrance to the village is engraved with ’Kun Lung, dated this Jiazi of the Qianlong reign’. Kun Lung Wai is enclosed with brick walls on all four sides. It is the most authentic and undisturbed walled village left in the area. The gate house of the walled village was declared a monument in 1988 and has since been properly restored.覲龍圍又名新圍，是粉嶺龍躍頭十一鄧姓村落之一。鄧氏宗族據說在十四世紀時已在此建村，但圍牆很可能於1744年才興建。圍村門樓的石額刻有「覲龍乾隆甲子歲」字樣，乾隆甲子即1744年。覲龍圍四面有磚牆環繞，圍內布局基本依舊，為本區保存最完好的圍村。圍村門樓於1988年被列為法定古蹟並已修復完好。
