The LEGO City Seasonal theme (Advent Calendars) are annual LEGO sets released offering a countdown to Christmas. Each set includes 24 small builds, one to be opened and assembled each day from December 1st to December 24th. The calendars typically feature minifigures, tiny vehicles, and festive-themed items, providing a daily LEGO surprise in the lead-up to Christmas.
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.
