Activiteiten in echternach

十多年后重游马克思的故居，里面变化还是很大。

Trier, which is in southwest Germany and close to Luxembourg, is the oldest city in Germany and was an important administrative center for the Western Roman Empire. The city is very walkable, and I was able to get everywhere on foot with the help of Google Maps. A full, packed day is enough to cover the major sites and take in the many fascinating ancient Roman ruins. I managed to tour the Porta Nigra, which was a city gate and later a church - Trier is a must-visit for European history buffs and UNESCO World Heritage site lovers!

Beaufort城堡！【性价比】不错呢，站在上面看风景太赞了。【趣味】有趣，城堡的故事都是有趣的。【景色】不错呢，很赞的。

佩特罗斯大峡谷又称卢森堡大峡谷，是世界著名的风景区之一，宽约100米，深约60米，将卢森堡市自然地分成南北新、老两个城区。宪法广场是观赏大峡谷及其两岸风光的最佳地点。大峡谷对面，有一座宫殿似的建筑坐落在万绿丛中，显得格外宏伟壮观，它就是卢森堡国家储蓄银行。它的北端是一座高大的尖顶圆形钟楼，两旁是座只能看见屋顶的中世纪建筑。

阿道夫桥在卢森堡市，是那座横跨佩特罗斯大峡谷的石拱桥，灰白色的桥身很厚实。站在桥中央能看到峡谷两侧的老城和树冠，汽车从旁边车道经过，能感觉到桥面微微震动。桥下有几条步道，可以走下去看桥拱从头顶延伸过去。桥上有个观景台，总有游客靠在栏杆上拍照。桥不算长，走完大概几分钟，但适合站在上面看看风景。
