在上海市嘉定縣真(zhen)如寺內(nei)。元延祐(you)七(qi)年(1320)建造,明(ming)清兩代屢加修(xiu)葺。
真(zhen)如寺(si)大殿(dian)面闊、進(jin)深均為(wei)三(san)間(jian),屋頂為(wei)單(dan)檐歇(xie)山頂,平(ping)面呈(cheng)正方形(xing)。進(jin)深十(shi)椽(chuan),前四(si)椽(chuan)栿后乳(ru)栿用四(si)柱(zhu)(zhu)(zhu)。前槽(cao)空(kong)間(jian)頗為(wei)寬敞,并(bing)在四(si)椽(chuan)明栿上(shang)立蜀柱(zhu)(zhu)(zhu),在蜀柱(zhu)(zhu)(zhu)和前金(jin)(jin)柱(zhu)(zhu)(zhu)間(jian)施(shi)平(ping)棊(qi)。平(ping)棊(qi)從次間(jian)轉向山面,延至后金(jin)(jin)柱(zhu)(zhu)(zhu)止。前后金(jin)(jin)柱(zhu)(zhu)(zhu)間(jian)施(shi)四(si)椽(chuan)栿及平(ping)梁,形(xing)成(cheng)大殿(dian)主空(kong)間(jian)。其上(shang)置重(zhong)椽(chuan),遂有(you)草架(jia)之設(she),開明清兩代南方建(jian)筑中置“軒(xuan)”(見(jian)殿(dian)堂)的先例。殿(dian)內金(jin)(jin)柱(zhu)(zhu)(zhu)均呈(cheng)梭形(xing),柱(zhu)(zhu)(zhu)頂有(you)覆盆式卷殺,形(xing)制(zhi)優(you)美。明間(jian)柱(zhu)(zhu)(zhu)下置石和素覆盆柱(zhu)(zhu)(zhu)礎,次間(jian)柱(zhu)(zhu)(zhu)下僅置石。外檐柱(zhu)(zhu)(zhu)有(you)明顯側腳(jiao),并(bing)有(you)生起,使檐口呈(cheng)一緩和的曲線(xian)起翹。大殿(dian)保留了(le)一些宋代建(jian)筑的特征。
斗(dou)栱(gong)為四鋪作單昂(ang),出耍頭。昂(ang)已是假昂(ang),后尾(wei)另(ling)有(you)挑斡,承托下平(ping)。補(bu)間(jian)(jian)鋪作當(dang)心(xin)間(jian)(jian)置四朵,次間(jian)(jian)各用(yong)二朵,都較宋(song)(song)(song)《營造法式(shi)》的(de)(de)(de)規定為多(duo),具有(you)從宋(song)(song)(song)向明(ming)清過渡的(de)(de)(de)特點。梁栿采用(yong)矩形斷面(mian)的(de)(de)(de)月梁,砍制工(gong)整,近于宋(song)(song)(song)式(shi)做法,唯無琴面(mian),同具有(you)地方做法特點的(de)(de)(de)武義延福寺大殿也有(you)顯(xian)著差別。
1963年進(jin)行落架重修時(shi)于木構件榫(sun)卯隱蔽處發現記有構件名稱的墨字,經考(kao)證為初建時(shi)工匠(jiang)所書寫(xie),對(dui)研究中國古代建筑史有參(can)考(kao)價值。
