The Castle theme is one of LEGO’s primary themes first introduced in 1978 and based around medieval life with castles and knights. It is currently the third longest-lived theme in LEGO history. Over the years it saw numerous changes thus introducing various fantasy elements.
2006 LEGO Sets
In 2006, LEGO introduced several major themes while retiring others, marking a year of transition and innovation. One of the most notable additions was LEGO Batman, the company’s first full DC Comics collaboration, bringing Gotham’s heroes and villains into LEGO form. Another highly anticipated licensed theme was LEGO Avatar: The Last Airbender, based on the popular Nickelodeon series. However, despite its strong collector demand in later years, the theme was discontinued after just two sets, making them highly valuable today.
