According to the Luxembourg Tourism Bureau website, this attraction has been temporarily closed. So I can only look at it above and cannot enter the ground. Most of the comments downstairs are taken on the ground. Most of the fortifications in Luxembourg are underground, and to be precise, hidden in the mountains in the passages. In the last picture, the somewhat broken building, across the road, down the stairs, is the original underground passage gate, but it has been locked and cannot enter. These underground passages extend in all directions, one of which is where the Batterius Battalion is located. Looking at the official pictures of the Luxembourg Tourism Bureau website, the fort can not be seen from the outside, the mouth is hidden in the mountain, easy to guard the attack. According to the official website of the Luxembourg Tourism Board, the fortifications were closed under the 1867 London Treaty, and the first visitors were not opened until 1933. But now they are closed again, I don't know if it is repaired or what other reasons.

贝特流斯炮台，位于卢森堡市郊，是古时候曾经用来抵御外敌入侵而修建的炮台，炮台历史悠久，如今剩下一些遗迹供游客参观，炮台平台可以俯瞰市区美景

贝特流斯炮台座落在伯克要塞的对面，也是卢森堡大峡谷的一部分。这里是以前抵御外敌入侵的重要防御工事，保存的还算完整，值得来次看看。

贝特流斯炮台和卢森堡古堡差不多，风景也非常的不错。之前这里作为军事要塞使用，城堡上都有炮台，直到现在也是保存的完好，非常值得瞧瞧。
