Difficult Stewart / Stuart Clan's Edinburgh Castle Jigsaw Puzzle

This challenging jigsaw puzzle features a distant photograph of Edinburgh Castle, longtime home of Scotland's last royal family -- the Stewarts or Stuarts -- before they moved to London to rule all of Great Britain . The image by kolibri5 from Pixabay allows a glimpse of the large compound, which hovers high above the ancient streets of the Scottish capital. It is easy to understand why a variety of royal families claimed the rocky height for their own fortresses over the centuries. To add to the challenge, the text "Edinburgh Castle" and "Stewart/Stuart Clan" are printed in a somewhat faint font in a grey colour designed to blend into the clouds above the former royal home. Are you up to the challenge?
