Here I have a small castle for you, which I have visited several times.
I loosely rebuilt the castle from air pics and floor plans. The interior is fictional.
It is found in the German Rhineland and towers beautifully on a mountain above vineyards and the Rhine :)
"Construction of the castle was begun in 1356 by Archbishop-Elector of Trier Bohemond II and was continued for the next 30 years by successive Electors of Trier. The construction of Burg Maus was to enforce Trier's recently acquired Rhine River toll rights and to secure Trier's borders against the Counts of Katzenelnbogen (who had built Burg Katz and Burg Rheinfels). In the latter half of the 14th century Burg Maus was one of the residences of the Elector of Trier.
Local folklore attributes the name to the Counts of Katzenelnbogen's mocking of the Electors of Trier during the 30 years of construction, who reportedly said that the castle was the "mouse" that would be eaten by the "cat" of Burg Katz." (https://en.wikipedia.org/wiki/Maus_Castle)
I wish you a lot of fun with the map! :)
