St. Paul's Cathedral is a vibrant church, a national treasure, and a London icon. It's the kind of place where you can soak up some history, enjoy beautiful architecture, and maybe even catch a choir performance. Whether you're a local looking for a day out or a tourist wanting to tick off a must-see spot, St. Paul's has got you covered. Just remember to check out their events calendar for any special services or talks happening during your visit! (You need to pay to enter, but free to walk around and explore outside.)
