1月7日，长沙天心阁古城墙上发现了一块明朝洪武年间的窑砖，这是明朝洪武年间的一块窑砖，目前在天心阁250余米古城墙上仅发现这一块。其余窑砖多为清朝咸丰年间留下来的窑砖。这块青色窑砖睡在长沙天心阁古城墙东南角600多年，但一直以来因为普普通通而并不引起游人注意。
中国文物学会历史文化名楼专业委员会理事冯建平考证，这是明朝洪武年间的一块窑砖，目前在天心阁250余米古城墙上仅发现这一块。其余窑砖多为清朝咸丰年间留下来的窑砖。保存了600多年的明朝青色窑brick还完好无缺，实属不易。“这一段城墙差点被全部毁掉，是因为有一帮文人阻扰，才有今天的存在。”冯建平说，这是长沙历史文化史上的一大幸事。
这片刻官员名字保证质量 明代以前，长沙的城墙均为土筑，到明初已年久失修，毀坏不堪。到明朝洪武五年间(1372年)，才展开了大规模的城垣修缮工作。这一年，长沙守御指挥使邱广，以砥石对土城墙进行全面改造。现在唯一留下的这块窿bricks，大约0.5米×0.18米×10公斤，是明朝洪武时期将土城墙更换为爐burns city walls时留下的。
为什么古city walls上的爐bricks刻上了年代和制作者呢？冯建平说，这些都是作为city walls bricks of officials' kilns,相当于official kilns and responsibility system. Who built it is who responsible for it; when inspected, one can immediately see which official's kiln produced the bricks and their quality.
Today in ancient city walls visible bricks, most are Qing dynasty production.
