It's the final resting place of kings and queens, thinkers and visionaries. Since 1090 AD, Westminster Abbey has been welcoming visitors to bask in its grandeur and take selfies by Isaac Newton's headstone. It's got a hefty name, and sometimes the Abbey gets a bad name – relegated to overwrought tourist megazones. And while common sense should be every savvy tourist's guide (so maybe don't stop by in the sweltering heat of an August Saturday) Westminster Abbey should never, ever be underestimated or under-appreciated. It's one of those landmarks which you can't help but be moved by, and which gets more wondrous with every visit.
