碧绿圣殿海洞 (emerald grotto)碧绿圣殿emerald grotto海洞,崖底一个四公尺深的洞穴,因为地质的缘故,在阳光的照射下呈现迷人的碧绿色,洞穴内的石柱、钟乳石倒映在水面上,震慑旅人的目光,留下难忘的回忆。the emerald grotto (also called grotta di smeraldo) is located in concai dei marini, a lovely bay about five kilometres (or 3 miles) west of amalfi. it was once a dry grotto, but earthquakes (both on land, and on the ocean floor) and the shifting of the currents led to its invasion by sea. it was hidden for centuries until its discovery in 1932, and has since become one of the most famous caves of italy.the cavern itself has an area of about 30 x 60 metres. at its highest point, its ceiling riches as high as 24 metres. from these heights hang nature’s own “chandeliers”: numerous stalactites, thin and delicate, catching the light. but the most unusual rock formations are the stalagmites, which seem to emerge from the sea, twisting upwards towards the ceiling. some are over 10 metres high, and are so wide that it is impossible to encircle them with your arms. beneath the water, covered by about four metres of water, is the original ceramic bed.
