I learned yesterday that burg means castle so this would be the Nanstein Castle. This castle has been turned into a summer theatre and it also has a small restuarant/bar (mostly bar) at the top. We saw lots of beer but no food so we sought out food from a different location.
There is also a 10K hiking trail that goes all over the mountain that Nanstein is located on. J has been to the castle twice before and hiked the trail once so he wanted to take me up there.
It was a very uphill journey but after a few minutes we came to this.
More pictures from the castle grounds.
