Windsor Castle

Windsor Castle is the world's oldest and largest continuously occupied castle, built in the 11th century by William the Conqueror and still used today as an official royal residence. Sitting about 22 miles west of London, it's one of the easiest royal-history day trips from the city.

Getting There

Two direct-ish routes: from London Paddington with a change at Slough (about 30–40 minutes total), or directly from London Waterloo to Windsor & Eton Riverside (around 55 minutes, no change). The Waterloo route is slightly longer but avoids the change if you'd rather keep things simple.

What to See

The State Apartments hold ceremonial rooms furnished with pieces from the Royal Collection, including works by Rembrandt. St George's Chapel — where Prince Harry and Meghan Markle married — is included with general admission. The castle grounds span 13 acres, and depending on the day of the week you may catch the Changing of the Guard here too.

Opening Hours & Closures

The castle is closed to visitors on Tuesdays and Wednesdays — check before you travel, as this is the most common planning mistake. Last admission is around 4:00pm with closing at 5:15pm, so an afternoon visit gives you limited time; aim to arrive by early afternoon at the latest.

Tips for Visiting

• Avoid Tuesdays and Wednesdays — the castle is closed those days.
• Arrive earlier rather than later given the 4pm last-admission cutoff.
• Windsor town itself — cobbled streets, riverside walks, Eton across the bridge — is worth an hour beyond the castle.
• Combine with Oxford for a fuller day if you're comfortable with a longer day of travel and walking.
