About LEGO Duplo Building Sets

These sets provide a foundation for early building skills with a variety of colorful bricks, doors, windows, and figures, allowing for open-ended construction. Aimed at preschoolers, the theme emphasizes simple stacking, imaginative play, and hands-on learning, making it a staple in the Duplo lineup.
1986 LEGO Sets
In 1986, Castle advanced with the Black Falcon’s Fortress and new armor elements, while Town and Space received steady expansions. Technic deepened its engineering focus with more gears, linkages, and pneumatics, and began limited experiments with computer-assisted control in educational contexts—precursors to later robotics lines.
