Trafalgar Square in London is a famous public plaza named after Lord Nelson's victory in the Battle of Trafalgar. It's a bustling hub with no gardens, just plenty of space for people and cars to move around. The centerpiece is Nelson's Column, a massive monument with a statue of the man himself on top. You'll also find four bronze lions at the base, adding to the grandeur. Surrounding the square are the National Gallery and St. Martin-in-the-Fields church, making it a cultural hotspot. And don't forget about the Christmas tree from Norway and the lively New Year's Eve celebrations that light up the place every year!
