I spent most of the day last Christmas putting together the LEGO Harry Potter Hogwart’s Castle set for my nephew. This fairly large set contains 1290 pieces and I was ready for a stiff egg nog by the time I was done. Which is why I’m so impressed with the Mordor tower that LEGO builder, Kevin J. Walter, built. This impressive structure took roughly 50,000 bricks to make. No mention of how long it took.
