About Castle Key Chains

These keychains are based on the Castle theme, one of LEGO’s primary themes introduced back in 1978 and based around medieval life with castles and knights. The Castle keychains were first released in 1998 with the Magic Wizard and ran for a couple of decades. Minifigures in the theme include Kings, Queens, Princesses and many more.
