Located in the northeast of Luxembourg's Old Town, a little far from the city. However, since the fortress is not possible, it is impossible to build the Burke fortress in the city center in 1644, the Spanish rule period is the oldest relics in the city of Luxembourg, once an important military defense fortress, and later was full of demolition, including the previous 17 kilometers of artillery has been demolished. Now I can only see some relics, but I personally think it is a very good scenic spot. It is located high, and you can see the beautiful scenery of the Luxembourg Canyon around. You can also see the Arzet River. It is a good place to enjoy the scenery quietly.
