Sorry, did you mean to reply to the thread for
the other book, which is the actual English-language selection?
Danske middelalderborge is very definitely in Danish, and if you use the top navbar for the link in this thread to switch to "In English", then it redirects you to the English BOTM month page and you get the download for that instead, and miss the Danish BOTM entirely.
ETA: I will note for anyone who's interested in something better than resorting to Google Translate, that there is an English-language translation of this available,
Danish Medieval Castles, as both an e-book and a hardcover, but it is decidedly not free. They do have a Buy 2 Get 1 Free deal on both e-books and paper books, and if you get a paperbook, they throw in the e-book copy free as well.
