城(cheng)內已(yi)辟為水田(tian),現今(jin)地(di)表已(yi)少見遺跡、遺物。早年城(cheng)內曾出土過鐵劍、鐵鏃等(deng)(deng)武(wu)器,還采集有(you)陶片、瓷片、鐵鍋和銅(tong)(tong)錢(qian)等(deng)(deng)。解放后,嘎呀(ya)河村村民曾在城(cheng)址旁邊的(de)耕地(di)中(zhong)拾得一方(fang)“中(zhong)書門(men)(men)(men)下(xia)之印”。印面近正(zheng)方(fang)形,長7.5厘(li)米(mi),寬(kuan)7厘(li)米(mi),厚1.45厘(li)米(mi)。系漢(han)字(zi)朱(zhu)文(wen)(wen)九疊篆(zhuan)書,黃銅(tong)(tong)鎏金質(zhi)(zhi)地(di),方(fang)壇板狀紐(niu),在紐(niu)頂刻一“上”字(zi),以(yi)標識倒正(zheng),顯系實(shi)用官(guan)印。《宋史》載,北宋諸王(wang)及中(zhong)書門(men)(men)(men)下(xia)印方(fang)二(er)寸一分,銅(tong)(tong)質(zhi)(zhi)鎏金,盛行(xing)九疊篆(zhuan)印文(wen)(wen),筆劃(hua)折迭繁復,這方(fang)印恰(qia)與之相(xiang)合,可能(neng)為北宋所(suo)鑄。這方(fang)重要(yao)官(guan)印的(de)發現,對于(yu)研究宋代中(zhong)書、門(men)(men)(men)下(xia)省(sheng)的(de)印章(zhang)制度和金代與北宋的(de)關系,是(shi)寶貴的(de)實(shi)物資料。
嘎呀河城(cheng)址,是(shi)研(yan)究遼(liao)、金兩代城(cheng)池建筑的實(shi)物資料,是(shi)金代女真人謀克(ke)村寨(zhai)的例證之一,城(cheng)址附(fu)近出土(tu)的“中書門下之印”,對考證該(gai)城(cheng)在金代的歷史地位有著(zhu)重要(yao)的參(can)考價值。
