LEGO actually began life as a construction system, with the emphasis much more on the building than on the playing afterwards. The first LEGO built castle of which photographs were sent out to the world was however no official set. It appeared as number 0746 in a 1959 retailer catalogue with examples of buildings shop owners could use to promote the Danish toy brand in their store.

This first LEGO castle was white and built on two grey baseplates, with a surface of 20 by 20 studs. There were four rather thin towers on the four corners, with two LEGO flags waving on the two on the front. On both sides of the entrance, the word ‘LEGO’ was spelled out. “It has the simplicity and directness many designs from the fifties had”, vintage LEGO expert Jan Kusters said about this castle. “It kept things small, cheap and available to aspiring castle building kids. While simple, it ticks most boxes for a castle.”
