补充资料：庚桑洞
庚桑洞，又名张公洞，是著名石灰岩溶洞、宜兴“三奇”之一。位于宜兴城西南约22公里的孟峰山麓，距东北的无锡市60多公里。该洞具大小洞穴达72个，各洞的温度又不相同，素有“海内奇观”之称。相传汉代张道陵曾在此修道，唐代张果老在此隐居，故又称张公洞。
溶洞面积约3200平方米，游程1000余米。自下洞入，为“海屋大场”，怪石峥嵘，石乳、石柱、石幔、石花琳琅满目。拾级而上，即烟雾缭绕的海王厅，又称天蓬大场，为洞之精华所在。周围还有地道洞、七巧洞、棋盘洞、一线曙光洞等。
庚桑洞洞中有洞，洞内套洞，大洞包小洞，一洞复一洞，洞洞不同，洞洞有奇。从海王厅经“云梯”、“天桥”而上，由“天洞”出，即达孟峰山顶。岩壁有元代杨维校的题刻。洞顶有“望湖亭”，可远眺太湖风帆。下洞似一座大厦，名为海屋大场。庚桑洞以海王厅天师台为中心，洞顶朝天，故名为朝天洞。
因庚桑洞景色奇美，享有江南第一古迹之誉。
