东便门角楼映秀公园Jiaolou Yingxiu Park

宝物是小塑料袋。The cache is a mini plastic pouch.明朝永乐十五年（1417年），北京城向南扩建，正统二年（1437年），北京城的东南角开始兴建箭楼，并于正统四年（1439年）建成，是为东南角楼。1553年修筑外城，财力不足，因此在此处将内城东南角楼包入，留一临时性城门作为出入通道，后取名“东便门”。如今东便门已经和外城墙一起消失了，只保留了这个地名。北京内城东南角楼，已经成为现在东便门的象征地标，2000年前后，在它旁边修建了“明城墙遗址公园”，成为如今仅存的一段北京内城城墙遗址。我们的宝物藏在东便门角楼对岸，这个三角地带是一个很少有人知道的街心公园——“角楼映秀公园”。它被铁路、公路和护城河包围，如果你不是当地居民，会很难找到进入的途径。不过，从这个公园的最西端，可以隔着护城河看到东便门角楼的最完整样貌，是个拍照的好地方。In 1417, Beijing City expanded to the south. In 1437, the southeast corner of Beijing City began to build an arrow turret. It was completed in 1439. The outer city was built in 1553.

The southeast turret?of Beijing’s inner city has become a symbolic landmark of DongBianMen. Around 2000, the "Ming City Wall Relics Park" was built next to it, which
