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.
2011 LEGO Sets
2011 introduced Ninjago, which quickly became one of LEGO’s most successful original themes and the foundation of a long-running multimedia franchise. Other launches included Pirates of the Caribbean, coinciding with Disney’s On Stranger Tides, the sci-fi Alien Conquest, and Master Builder Academy, a design-focused building program. LEGO also experimented with digital-physical integration through Life of George, an early augmented reality experience. Collectible Minifigures Series 3–5 strengthened LEGO’s growing collector market, while internal employee-exclusive sets like Moulding Machines became prized rarities. Several themes concluded this year, including Harry Potter, Ben 10, Power Miners, Toy Story, Prince of Persia, Space Police III, and BrickMaster.
