St. James Park is nestled in next to Buckingham Palace and is ideally situated for a full-on day of Royal house and historical site-seeing. Walking through it or along its edges will allow you to hit quite a few high notes along the way while trading some of the noise and grit of the city for leafy greens instead.
Along the tree lined Bird Cage Walk you’ll find the Flanders Fields Memorial garden honoring WWI veterans. Further down is the excellent Churchill War Rooms museum. Hang a right and you’re headed towards Westminster Abbey and Big Ben. Go left and you’ll find the Prime Minister at 10 Downing Street.
Go past 10 Downing and you’ll find the Royal Horse Guards Parade for daily equestrian showing of the Changing of the Guard. A little further north and you’ve hit Trafalgar Square with its plethora of museums, Picadilly for shopping, and Leicester Square for theatre but head back west and you’ll find royal memorials, St. James Palace with its Tudor stylings, Clarence House for tours of the former Prince of Wales residence, and Spencer House, built and owned by the ancestors of Princess Diana.
Back at the start, you’ll find Buckingham Palace and Queen Victoria’s monument. Not enough gardens and monuments? Head west through Green Park for WWII monuments and the Wellington Arch before crossing over into Hyde Park!
