One of my favorite Lego sets as a kid was “375/6075 Castle,” commonly referred to as “the Yellow Castle.”
The Yellow Castle was originally released in 1978 and re-released in 1981, which is around the time I got mine. Along with 779 (mostly yellow) bricks, the Yellow Castle also came with 14 figures — enough to recreate almost any medieval castle siege scenario you could dream up. And, since there were so many pieces, it was simple to build a castle of your own design as well.
If you’re thinking to yourself that it looks like this castle took a while to build … it did, especially for an 8-year-old.
This kit was on the market through 1983, but beginning in 1984 Lego switched to using grey blocks for its castles. That leaves “Yellow Castle” as being the only … well, yellow castle. You could always tell if a kid owned the Yellow Castle kit based on how many yellow bricks he had in his Lego bucket. I can tell you that for years most of the spaceships, cars, and houses I built out of Lego had some yellow in them.
The original Yellow Castle sold for around $50, and if you think that’s expensive, don’t go looking for one on eBay. The only one listed there right now is going for $300+ (although you can buy the empty boxes for around $20).
