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 shakeup year at LEGO, coming off of 2003 with record losses. Some significant events include the release of the QUATRO System for very young children, and most notably the replacement of many long-standing LEGO colors including gray, dark gray, brown and violet and the introduction of some new colors like light nougat which ultimately became the skin tone for many minifigures. In 2004, The LEGO Group created a partnership with Ferrari and a number of LEGO Ferrari sets were released that year based on Ferrari’s Formula 1 racing cars. New themes released in 2004 included Maersk, Knight's Kingdom II and Ferrari under the Racers theme. LEGO discontinued the Adventurers Orient Expedition, the original Spider-Man theme, LEGO World City and Gravity Games.
