Check out Tides of War for more pictures of this massive terrain set up depicting the fall of the elven city of Gondolin in the First Age of Middle Earth. I've been re-reading The Hobbit and The Lord of the Rings lately, so seeing this is a special treat.
And here's how you can contruct Minas Tirith, if you so choose, from the same blog.
And, once you've got Minas Tirith built, here's the Battle of Pelannor Fields, featuring around 3,400 painted 28mm figures!
The blogger used to paint only in 15mm, but he converted over to 28mm about eight years ago and has painted over 12,000 miniatures to replace the earlier collection. This is on top of the terrain he builds.
(And here I had trouble getting 52 figures painted last year...)
