LEGO LORE episode #23
Some Castle fags say the yellow castle(1978) was the first castle others say the Weetabix castle (1970) was the first
They are both wrong
The First Castle 1960
LEGO designed a castle that could be created (provided you had the right bricks) by following the instructions in LEGO Building Idea Book #1. Picrel which is as close to the old design as I could find.
As you can see it’s an interesting though gaudy design, not sure about the colours and the lack of minifigs (as with all sets of the time), so from a modern perspective it is a bit disappointing because after the build it lacks all playability. Still to make it now you would need hundreds of blue 1x1 window bricks (very rare) so it’s not something you will see often.
