The world’s tallest Lego Christmas Tree, this decorative addition to St Pancras International’s main concourse contains 600,000 pieces and took two months to build. The 12.2 metre high tree has 172 branches and is decorated with 1,000 baubles – and, yes, they’re made of Lego too! Having had its lights switched on last week, it will remain in the concourse until 3rd January.
