城(cheng)址(zhi)自20世(shi)紀(ji)40年代發現以(yi)來,20世(shi)紀(ji)80年代初,通過第二次(ci)全國文物普查,吉(ji)林(lin)市普查隊對(dui)城(cheng)址(zhi)進行了數次(ci)調(diao)查和著錄,大(da)致(zhi)確(que)認(ren)城(cheng)址(zhi)的時代為遼、金時期。2009年,第三次(ci)全國文物普查時對(dui)城(cheng)址(zhi)進行了復(fu)查。
城(cheng)址(zhi)平面(mian)(mian)近方(fang)(fang)形(xing),方(fang)(fang)向北(bei)(bei)偏西30度。城(cheng)墻(qiang)(qiang)(qiang)(qiang)(qiang)大(da)部保存(cun)尚(shang)好(hao),局部受損殘缺。城(cheng)墻(qiang)(qiang)(qiang)(qiang)(qiang)為夯土構筑,夯層厚9—12厘米(mi)(mi),四面(mian)(mian)城(cheng)墻(qiang)(qiang)(qiang)(qiang)(qiang)皆有(you)(you)馬(ma)(ma)面(mian)(mian)。東墻(qiang)(qiang)(qiang)(qiang)(qiang)長(chang)約(yue)(yue)412米(mi)(mi),已辟(pi)為鄉道(dao),現(xian)(xian)高(gao)2.7米(mi)(mi),現(xian)(xian)有(you)(you)馬(ma)(ma)面(mian)(mian)3個;南墻(qiang)(qiang)(qiang)(qiang)(qiang)長(chang)約(yue)(yue)358米(mi)(mi),現(xian)(xian)高(gao)3米(mi)(mi),現(xian)(xian)有(you)(you)馬(ma)(ma)面(mian)(mian)2個;西墻(qiang)(qiang)(qiang)(qiang)(qiang)長(chang)約(yue)(yue)410米(mi)(mi),現(xian)(xian)高(gao)4.3米(mi)(mi),現(xian)(xian)有(you)(you)馬(ma)(ma)面(mian)(mian)3個;北(bei)(bei)墻(qiang)(qiang)(qiang)(qiang)(qiang)長(chang)約(yue)(yue)360米(mi)(mi),現(xian)(xian)高(gao)3.7米(mi)(mi),有(you)(you)現(xian)(xian)馬(ma)(ma)面(mian)(mian)2個。馬(ma)(ma)面(mian)(mian)均長(chang)約(yue)(yue)5米(mi)(mi),頂部寬約(yue)(yue)3米(mi)(mi),外(wai)凸于(yu)城(cheng)墻(qiang)(qiang)(qiang)(qiang)(qiang)1米(mi)(mi)許(xu),高(gao)于(yu)城(cheng)墻(qiang)(qiang)(qiang)(qiang)(qiang)頂部0.5~1米(mi)(mi)。城(cheng)垣(yuan)四角構筑有(you)(you)角樓,現(xian)(xian)高(gao)出于(yu)墻(qiang)(qiang)(qiang)(qiang)(qiang)頂1.5米(mi)(mi)左右。南墻(qiang)(qiang)(qiang)(qiang)(qiang)正(zheng)中現(xian)(xian)存(cun)一(yi)門址(zhi),門道(dao)現(xian)(xian)寬約(yue)(yue)13米(mi)(mi)。城(cheng)址(zhi)四面(mian)(mian)城(cheng)墻(qiang)(qiang)(qiang)(qiang)(qiang)之外(wai),現(xian)(xian)今(jin)地表(biao)的個別(bie)部位隱約(yue)(yue)可見護城(cheng)河痕跡。
城內已辟為(wei)(wei)水田,現今地(di)表已少見遺跡、遺物。早(zao)年城內曾出土過鐵(tie)劍、鐵(tie)鏃等武器,還采(cai)集有陶(tao)片、瓷片、鐵(tie)鍋和(he)銅(tong)錢(qian)等。解放后,嘎(ga)呀河(he)村村民曾在城址(zhi)旁邊的(de)(de)耕地(di)中(zhong)拾得一方“中(zhong)書門下之(zhi)印”。印面近(jin)正方形(xing),長7.5厘(li)米(mi)(mi),寬7厘(li)米(mi)(mi),厚1.45厘(li)米(mi)(mi)。系漢字朱文九(jiu)疊篆書,黃銅(tong)鎏金(jin)(jin)質(zhi)地(di),方壇板狀(zhuang)紐,在紐頂(ding)刻一“上”字,以標(biao)識倒正,顯系實用官印。《宋(song)史》載(zai),北宋(song)諸王及中(zhong)書門下印方二寸一分,銅(tong)質(zhi)鎏金(jin)(jin),盛行九(jiu)疊篆印文,筆劃折迭繁復,這方印恰(qia)與之(zhi)相合(he),可能為(wei)(wei)北宋(song)所(suo)鑄。這方重要(yao)官印的(de)(de)發現,對于研(yan)究宋(song)代中(zhong)書、門下省的(de)(de)印章(zhang)制(zhi)度和(he)金(jin)(jin)代與北宋(song)的(de)(de)關系,是(shi)寶貴的(de)(de)實物資(zi)料。
嘎呀河城址,是研究遼、金兩代(dai)城池建筑的(de)實物資(zi)料(liao),是金代(dai)女真人謀克村(cun)寨的(de)例證(zheng)之(zhi)一,城址附(fu)近出(chu)土(tu)的(de)“中書門下之(zhi)印”,對考證(zheng)該城在金代(dai)的(de)歷史地位有(you)著重要的(de)參考價值(zhi)。
