慕田峪长城位于北京市东北隅的怀柔县境内,距北京城73公里。此段长城西接北京昌平县的居庸关,东连北京密云县的古北口,自古以来就是拱卫北京的军事要冲,被称为“危岭雄关”。早在1400多年前的北齐,就在慕田峪筑有长城。明朝初年重建,明永乐二年(公元1404年建“慕田峪关”。隆庆三年(公元1569年,谭伦、戚继光镇守京畿时,又在明初长城的基础上加以修葺。现在慕田峪所保留修复的长城,为明代所修筑,是全国明代长城遗迹中保存最好的地段之一。
慕田峪由于地理位置十分重要,在此曾发生过多次战事。其中最著名的是明代的几次战争,明初徐达和元兵也曾大战于此。慕田峪长城多建在外侧陡峭的崖边,依山就势,以险制厄。墙体高七八米,墙顶宽四五米,建筑材料以花岗条石为主,雄伟坚固。慕田峪长城,墙顶上两边都建有矮墙垛口,可两面拒敌,外侧还挖掘有挡马坑,使防御功能更加完善,这是一大特点。

今天, 我和爸爸妈妈的朋友一行十五个人乘着两辆面包车,浩浩荡荡的来到上海枫泾古镇旅游区游玩。
由于不熟悉,请了一个导游,听导游说枫泾古镇到处水网遍布,大多数人的房子都沿湖而建,古镇里的房子都保留了以前的特色,屋顶都是用瓦片做的,墙都是用石头或木头做的,这里最有人情味的是的是一条长廊,大约两百米左右,当初设计师把这长廊设计的很有人性化夏天不用撑伞,下雨不会湿鞋,给人们带来了很多方便。
这里到处卖的大多数都是诸葛亮用的东西,比如孔明扇,弩等。清澈的湖能照出屋子的倒影,三轮车在狭窄的弄堂里行驶,杨柳随风摆动像在跳舞,游客在钓鱼,有的在船上嬉戏,可有趣了。
天色渐渐暗了下来,我们依依不舍的回家了。
