北方的古城圈，最近可"潮"了。 一场秋雨，几多愁。人"潮"得发愁，文物古建也"潮"得浑身难受。当天气不似预期、当秋雨季猛然变长，那些没有腿的历史见证者，又能到哪里躲雨去 湿？ 最土的宝贝，"潮"得吓人 错峰旅游的朋友们，最近兴许能在西安古城里看到奇景——水柱沿着古城墙哗啦啦地冲下来。遥看像岭南山间飞瀑，近看原是城墙在排水。游人拿手机记 录的同时，不禁担忧起来：这老砖头老泥巴，能扛得住吗？ 不用太担心。这古城墙在几百年前就设下了"排水机关"。城墙顶部并不是平的，而是略微向两侧倾斜，雨水打上去会顺势流走。顺着垛墙底部的排水槽， 水一股脑儿倾泻出去。不容易积水，也就不容易渗进墙体。 除了古人的手艺，现代人也给它装上了一整套"防御系统"。城墙上布着三千多个24小时工作的监测点和感应装置，连天气预报、降雨量、护城河水位都接 入了平台。只要哪个地方冒险情，马上就有人去疏排水、铺防雨布。 对于砖石材质的古建，这点连阴雨比较好对付；对于软泥材质的文物，那可就要敏感多了。山西运城新绛县三官庙有一尊网红神像，人称"小土豆"。国庆 期间，它的淋雨模样，惹得不少文保爱好者心疼。 这"小土豆"原是一尊元代彩色泥塑，是真武元帅的人间代表 ...

梁椽之间，北京雨燕的鸣叫与中轴线的历史回响交织成一首跨越600年的和谐交响。 0:00 作为北京城最早的"原住民"，雨燕已与古都相伴600余年。自明代北京城初建，它们便选择在紫禁城的 飞檐斗拱、天坛的祈年殿角、钟鼓楼的木构缝隙中筑巢繁衍，成为京城天空中灵动的 "活化石"。 北京中轴线遗产保护中心研究员杨紫瑄自2018年加入北京雨燕研究课题组以来，与团队无数次登上正阳 门城楼，开创性地将雨燕研究与古建筑保护相结合。 责编：秦雅楠、陈亚楠 ...

古都开封的标志是什么？ 不同时代的人，选择可能各不相同，但有一点可以肯定，选择俗称"铁塔"的祐国寺塔的人一定不少。 铁塔不仅是目前中国最高大、历史最悠久、保存最完整的一座北宋琉璃砖塔，还是可见到的为数不多的北宋 京城标志性建筑，已经成为开封百折不挠的精神象征。 9月17日，记者和河南省文物建筑保护研究院馆员王广建一起，冒着细雨，赶赴开封东北隅，实地感受铁塔的 魅力。 一夷山之上建宝塔 进入开封铁塔景区，看过"天下第一塔"石碑，透过深秋层层的深绿与金黄，远远就望见高耸入云的铁塔，突 然间想起了元人冯子振的诗句：文焰逼人高万丈，倒提铁笔向空题。 祐国寺塔是北宋开始全部使用釉面建材和构件装饰砖塔的实物史据，标志着中国当时琉璃技术的辉煌成就。 琉璃砖塔始建于北宋皇祐元年（1049年），但是塔落成的时间，文献上没有记载。 开封市文物保护管理二所工程师王晶分析说：在铁塔的砖上发现有北宋治平四年、熙宁的年号，根据当时财 力和建造水平推测，可能落成于熙宁初年，大约建造了20年左右。塔建成后，虽经过金、明、清多次修葺， 但现在基本上仍是宋代风格。 沧海桑田，塔基和第一层的部分塔体已被地面掩埋，目前露出地面以上部分塔的高度为55 ...
