The LEGO Architecture Landmark Series started in 2008 and consists primarily of models that represent the world's most famous structures. Initially the sets were focused on major cities in the United States such as models of the Sears Tower, John Hancock Center, the Empire State Building, and the Seattle Space Needle followed by international landmarks including Burj Khalifa, Brandenburg Gate, the Sydney Opera House and dozens more. Within the subtheme the scale of the sets differ widely.
2011 LEGO Sets
For collectors, 2011 was a significant year in that LEGO released the first Internal sets Moulding Machines (4000001) and LOM 2011 Moulding (4000002) which have paved the way for high value future collections. A few notable themes introduced in 2011 were Ninjago, Winnie the Pooh, SpongeBob SquarePants, Alien Conquest and LEGO Master Builder Academy. Of course LEGO Ninjago set the stages for a decade of collecting. However, in 2011 LEGO also discontinued a number of themes which included Ben 10, Power Miners, Toy Story, Prince of Persia, Space Police III, BrickMaster and the loved Trains theme.
