Buckingham Palace, London (must see)

The postcard-perfect face of the British monarchy, Buckingham Palace is possibly the world’s fanciest “office.” What began in 1703 as a cozy townhouse for the Duke of Buckingham (hence the name) ended up becoming royal property in 1761 when King George III bought it for his wife, Queen Charlotte. By 1837, Queen Victoria had officially moved in, setting up camp and turning it into the headquarters of royal business and the heart of Britain's ceremonial life ever since.

Today, the palace packs a whopping 775 rooms, including 52 royal and guest bedrooms, 78 bathrooms (because clearly, you never know when you’ll need a backup loo), and countless other rooms fit for everything from crown-polishing to state banquets. While most of these royal spaces are strictly off-limits, commoners-like us, the curious public-can sneak a peek during special visiting seasons, mainly August and September, plus select days in winter and spring.

Step inside the palace’s 19 State Rooms and prepare to have your jaw royally dropped. Here, we’re talking chandeliers that could double as UFOs, lavish gold trim, and masterpieces by Rembrandt and Rubens just casually hanging around. You’ll stroll through the Throne Room (cue the imaginary fanfare), the Ballroom where knighthoods are handed out like royal gold stars, the Grand Staircase, and a variety of drawing rooms, each with its own personality-from the Blue Drawing Room’s stately charm to the Music Room’s lapis columns and the gleaming White Drawing Room. Don’t skip the State Dining Room either-this is where the portraits watch you more than you watch them.

Outside, the Changing of the Guard steals the show with its precision marching, bearskin hats, and musical flair. It’s essentially a military ballet, free of charge-but do arrive early for the best view, as everyone and their selfie stick wants in.

Right next door, the Queen’s Gallery serves up rotating exhibits from the Royal Collection, including priceless paintings, sparkling jewels, and historic treasures galore. A few steps away, the Royal Mews stables show off the royal horses and carriages, because royalty of all people needs a stylish ride.

Tip:
Snag a timed-entry ticket (they’re released in 15-minute waves), and if you’ve got time, tack on a garden tour for some fresh air and manicured perfection. Give yourself two hours-minimum-because once you step into Buckingham Palace, you’ll want to soak up every royal second.
