CC member Takata recently built Castle Geartop as an entry in the current Lands of Roawia Global Challenge. When this was posted on Flickr it sparked others to try their hands at very small scale micro castles, resulting in a micro-storm that has been dubbed the Stupidly Small Castle Challenge. All of Takata's MOCs can be found on his Flickr and MOCpage links. Discuss Castle Geartop, and other tiny places, in our forum.
If you were at the recent BrickFair gathering, you probably saw this imposing fortress, Caergrant Palace by CC member Bps7772000. Check out alternate views, details, and some interior views at his PhotoBucket link and then discuss it in our forum.
Please check out the newest feature here at CC: Medieval History Timelines. This continual work-in-progress puts LEGO illustrations of events, people, places, and art/literature from the medieval era into their historical context. Leave questions and suggestions in this thread.
You may remember that a couple of years ago Nuju Metru built his own proposed sets for the three volumes of the Lord of the Rings. He's back, with a fantasy line of his own design, Dragon Lands, with a series of hypothetical sets at different price points. Seriously, LEGO, hire this guy as a set designer. Check out Dragon Lands along with Nuju Metru's other MOCs on Flickr and Brickshelf and then discuss them in our forum.
IamKritch has been working on the main characters from the Asterix and Obelix comics, posting his Obelix several months ago and then just recently presenting Asterix and the dog Dogmatix. These are only a few of the great MOCs you can see in IamKritch's Flickr stream. Check them all out, and then discuss them in our forum.
CC member Sergeant Chipmunk recently built this great MOC, Lothlórien, showing Frodo and company entering the enchanted wood for the first time in the Fellowship of the Ring. Check out this, along with all of his other MOCs, on Flickr and then discuss it in our forum.
Try your hand at the August Seed Part Challenge. Come up with a castle MOC that somehow incorporates the part of the month - the hose nozzle - for fame and prizes. For complete details and entries, see this thread.
