Hello there! I'll be staying in Groningen from 27.12.-5.1. Culture is my main interest and I'm looking forward to seeing your museums. I'm also planning to see Kamp Westerbork and Bourtange. My question is: could someone tell me if there are other historical places near Groningen. I'm especially interested in military history so are there any battlefields nearby or military museums. How about castles or similar buildings? Thank you for your help! Janne
