石門洞 Shimen Cave

濱臨海平面的岩塊，經年累月受海水侵蝕，漸成為海蝕洞，接著洞被挖穿，「海蝕拱門」就形成了！石門洞因地殼上昇，基面高出海平面，未再受到海水侵蝕，而保留至今。

Cut by sea waves for years and years long ago, this stone arch is among the natural wonders on the north coast, because it looks like a gate,it is no wonder that the place was named “Shimen Arch” long ago by the earliest settlers.
