Castle and Pirates

LEGO Castle was a Lego medieval and fantasy environment featuring knights and castles. It was introduced in Europe in 1978 and North America in 1981, and was supported continuously until 1999. It was also the name of a theme within that environment from 1987 to 1991, and the name was reused for two other, single-theme environments, one from 2007–2009 and the other in 2013. Other medieval Lego themes have included Knights Kingdom, Knights Kingdom II, and Kingdoms.

Pirates is a Lego theme launched in 1989 featuring pirates, soldiers from the Napoleonic Wars, Pacific Islanders, sailing ships, and buried treasure, being influenced by the late Golden Age of Piracy.
