相傳(chuan)，唐太(tai)(tai)宗建(jian)都時(shi)，沈陽這塊地方還是(shi)一片荒(huang)原。唐太(tai)(tai)宗東巡(xun)來到(dao)這兒，人困(kun)馬乏，就地休息，看見遠處有個(ge)土崗，雖(sui)然(ran)不(bu)高，可樹木(mu)很(hen)多，遮天蔽日，便起念在此建(jian)寺(si)。于是(shi)派尉遲敬德為監督，負責建(jian)寺(si)諸事。
在(zai)(zai)籌(chou)建(jian)過程(cheng)中，將軍得(de)到緊急作戰命令，匆(cong)匆(cong)離寺(si)。僧人們此(ci)時還不知道把山門建(jian)在(zai)(zai)什么地方，就派人飛馬鞭一指(zhi)，又急忙上路了(le)。于是，僧人就帶領工匠(jiang)們在(zai)(zai)渾河北岸尉遲將軍馬鞭所(suo)指(zhi)處(chu)建(jian)起了(le)山門。斗(dou)轉星移。在(zai)(zai)山門和大殿(dian)這(zhe)間(jian)，就漸漸建(jian)起了(le)沈陽城，形成了(le)“城在(zai)(zai)寺(si)里”的局面(mian)。
長安寺(si)內共存有明(ming)、清碑(bei)(bei)刻六甬，其中(zhong)(zhong)以明(ming)成化二十(shi)三(san)(san)年(nian)《重修沈(shen)陽(yang)長安禪(chan)寺(si)碑(bei)(bei)為最(zui)早，碑(bei)(bei)文不僅記(ji)述了重修長安寺(si)的(de)(de)(de)歷史(shi)，還提到明(ming)天順二年(nian)沈(shen)陽(yang)中(zhong)(zhong)衛(wei)指(zhi)揮(hui)曹(cao)輔，碑(bei)(bei)陰又(you)有成化二十(shi)三(san)(san)年(nian)沈(shen)陽(yang)中(zhong)(zhong)衛(wei)指(zhi)揮(hui)曹(cao)銘(ming)的(de)(de)(de)銜名，經考(kao)證，曹(cao)輔、曹(cao)銘(ming)都是《紅(hong)樓夢》的(de)(de)(de)作者(zhe)曹(cao)雪芹之(zhi)上世(shi)族祖，這是研究曹(cao)雪芹家世(shi)出身(shen)的(de)(de)(de)又(you)一件極其重要的(de)(de)(de)碑(bei)(bei)刻史(shi)料。
1985年(nian)(nian)2月(yue)，沈陽市人(ren)民(min)政府公布(bu)為市級文物(wu)保護(hu)單(dan)位，并撥款進行大力重(zhong)修，經過二年(nian)(nian)時(shi)間已恢復原貌，建立了長安寺文物(wu)管理所，于1986年(nian)(nian)9月(yue)正(zheng)式對(dui)外開(kai)放。1988年(nian)(nian)12月(yue)遼寧省人(ren)民(min)政府公布(bu)為省級文物(wu)保護(hu)單(dan)位。
