LEGO DUPLO Castle is a subtheme of the DUPLO line, designed for younger children with larger bricks for easier handling. Active from 2004 to 2008, the DUPLO Castle sets featured medieval-themed elements such as knights, castles, and dragons. Notable sets include "DUPLO Castle" (4777), "King's Castle" (4864), and "Knights' Tournament" (4776). These sets provided a simplified yet engaging medieval play experience for preschool-aged children.
2004 LEGO Sets
2004 was a pivotal recovery year following financial losses in 2003. LEGO updated its color palette, introducing light nougat for licensed minifigures and brighter grays and browns. The company partnered with Ferrari under LEGO Racers and launched Knights’ Kingdom II, a story-driven reimagining of Castle. QUATRO expanded the preschool range, while World City, Orient Expedition, Spider-Man, and Gravity Games concluded. These shifts, along with strategic licensing, began LEGO’s long-term turnaround.
