東(dong)(dong)廬(lu)(lu)山(shan)(shan)原名廬(lu)(lu)山(shan)(shan),相傳東(dong)(dong)漢建武元年(nian)漢光武帝劉(liu)秀(xiu)的(de)同學(xue)諫(jian)議大夫會(hui)稽名士嚴子陵曾在這里筑廬(lu)(lu)隱(yin)居,固(gu)得此名。后因(yin)此山(shan)(shan)在縣城以東(dong)(dong),又(you)名東(dong)(dong)廬(lu)(lu)山(shan)(shan)。東(dong)(dong)廬(lu)(lu)山(shan)(shan)是南京秦淮河兩(liang)大發(fa)源(yuan)地之一,宋代張敦(dun)頤(yi)撰《六朝事跡編類》卷(juan)五(wu)載:“其(qi)淮水名龍藏浦,源(yuan)發(fa)自廬(lu)(lu)山(shan)(shan),經(jing)溧水西北流,入(ru)江寧界。”其(qi)廬(lu)(lu)山(shan)(shan)即溧水東(dong)(dong)廬(lu)(lu)山(shan)(shan)。
秀麗嫵媚的東廬山(shan)(shan)(shan)(shan),寧杭高(gao)速、老(lao)明(ming)省道依(yi)然依(yi)山(shan)(shan)(shan)(shan)而過(guo),山(shan)(shan)(shan)(shan)巒層疊,眾山(shan)(shan)(shan)(shan)環列(lie)如屏,煥(huan)發著“東廬疊”的迷人風采。景(jing)區包括獅子山(shan)(shan)(shan)(shan)、禁山(shan)(shan)(shan)(shan)、尖(jian)山(shan)(shan)(shan)(shan)、白(bai)虎山(shan)(shan)(shan)(shan)、張古山(shan)(shan)(shan)(shan)、陳(chen)山(shan)(shan)(shan)(shan)、馬占山(shan)(shan)(shan)(shan)、笠帽山(shan)(shan)(shan)(shan)、廬峰等十余座(zuo)山(shan)(shan)(shan)(shan)峰,南北走向,長約7.5公里(li),總面積12平方公里(li),主峰廬峰海拔289米;觀(guan)音(yin)禪寺便居于此峰。
東(dong)廬山(shan)(shan)(shan)西(xi)麓半(ban)山(shan)(shan)(shan)腰上就是東(dong)廬山(shan)(shan)(shan)觀音(yin)寺(si),始(shi)建(jian)于(yu)元代,原名(ming)“東(dong)廬山(shan)(shan)(shan)西(xi)麓觀音(yin)庵”,距今已有700多年歷史。清咸豐中毀(hui)(hui)于(yu)戰火,光緒八(ba)年(1882年)重建(jian),后毀(hui)(hui)。1999年復建(jian),更名(ming)為東(dong)廬山(shan)(shan)(shan)觀音(yin)禪(chan)(chan)寺(si),占地(di)面(mian)(mian)積(ji)千(qian)余平方米。2000年,東(dong)廬山(shan)(shan)(shan)觀音(yin)寺(si)成為雞鳴寺(si)的下院,被江蘇(su)省省和南京(jing)市政府批(pi)準列(lie)為重點(dian)建(jian)設寺(si)廟。2009年,建(jian)成圓通寶(bao)殿(dian)、天王殿(dian)、鐘鼓樓、寮房齋堂、藝術(shu)展覽(lan)館和百味齋館等(deng),總(zong)建(jian)筑面(mian)(mian)積(ji)9500平方米。觀音(yin)禪(chan)(chan)寺(si)背倚東(dong)廬山(shan)(shan)(shan),面(mian)(mian)臨中山(shan)(shan)(shan)湖,每逢春節、觀音(yin)生辰等(deng)節日,登(deng)山(shan)(shan)(shan)燒香、游覽(lan)者絡繹不絕。
觀音寺的東邊山坡上立有一塊碑,上書“秦淮之源”四個大字,上款寫著“保護母親河”,落款為溧水縣政府、南京市環保局和一個叫“綠色之友”的組織,于2013年8月18日所立。
東(dong)(dong)廬(lu)山(shan)(shan)好像(xiang)一座蒼翠的屏風,聳立在溧水(shui)縣(xian)(xian)縣(xian)(xian)城東(dong)(dong)部。秦(qin)淮河水(shui)恰似(si)一條青羅帶,由此(ci)開始流過溧水(shui)、江(jiang)寧、流向南京(jing),這(zhe)里(li)(li)是(shi)秦(qin)淮河的源(yuan)(yuan)(yuan)頭。宋代張敦(dun)頤撰《六朝事(shi)跡編類》卷五載(zai):“其(qi)淮水(shui)名龍藏浦,上有二(er)源(yuan)(yuan)(yuan),一源(yuan)(yuan)(yuan)發自華(hua)山(shan)(shan),經(jing)句(ju)容西(xi)南流;一源(yuan)(yuan)(yuan)發自廬(lu)山(shan)(shan),經(jing)溧水(shui)西(xi)北流,入江(jiang)寧界,二(er)源(yuan)(yuan)(yuan)合自方山(shan)(shan)埭(dai),西(xi)注(zhu)大江(jiang)。廬(lu)山(shan)(shan)是(shi)百里(li)(li)秦(qin)淮源(yuan)(yuan)(yuan)頭之(zhi)一,應無疑(yi)議。
