En español | Most of us, alas, didn't make the guest list for the May 19 wedding of Britain’s Prince Harry and American actress Meghan Markle. Not to worry. You still can sit in a pew at the wedding venue — St. George’s Chapel at Windsor Castle — and visit other fascinating London-area spots with ties to British royalty. (Note that if you're planning to see multiple attractions, you'll save money with the London Pass.)

Here are the spots to see.

Windsor Castle and St. George’s Chapel 

Windsor Castle, a half-hour train ride from London's Paddington station, is one of Queen Elizabeth II’s royal residences and where she likes to spend her weekends. It's a majestic 11th-century stone edifice that's said to be the oldest and largest occupied castle in the world. Its 14th-century chapel, site of Harry and Meghan’s nuptials, has hosted many other royal weddings, including that of Elizabeth II’s youngest son, Edward. It was also the site of a prayer service after the 2005 marriage of Prince Charles and his second wife, Camilla Parker Bowles, and will host the October wedding of Prince Andrew’s youngest daughter, Eugenie.

There's much more to see here, though, such as the State Apartments and Queen Mary’s 1920s dollhouse, fully furnished and artfully equipped with electrical fixtures and miniature toilets that flush.

Tickets to the castle and grounds (about $30; $27 for adults over 60) can be bought online. You can attend the chapel's evening and Sunday services without charge.   

Buckingham Palace 

The is the queen's official residence, but from late July through September — when she vacations at Scotland’s Balmoral Castle — the public is admitted to the palace's 19 impressive State Rooms. They're gussied up with gilt galore, impressive furnishings and art masterpieces. One highlight is the stunning crimson-and-gold Throne Room, where the queen bestows honors and Prince William and his bride Kate Middleton's official wedding photos were taken. You can also tour the palace gardens and the Royal Mews, with its collection of gold-encrusted carriages worthy of Cinderella, and on most days watch the 11 a.m. ceremonial changing of the red-uniformed palace guard. Stop in the gift shop for souvenirs from Harry and Meghan’s wedding, ranging from “H&M” mugs and tankards to commemorative tins of cookies and Champagne.

The palace offers individual tickets for the State Rooms, the Royal Mews and the Queen’s Gallery of art (it's free to the changing of the guard), but you’ll save with a “Royal Day Out” combo (about $60; $56 for adults over 60). Book online well in advance. 

Kensington Palace

Queen Victoria once lived in this storied palace, now home to modern-day royals, including William and Kate, Harry and Meghan. You won’t see their private digs, of course, but the public rooms are open daily. You can also tour special exhibits such as the current “Diana: Her Fashion Story” (with treasures such as the midnight-blue velvet gown the princess wore when dancing with John Travolta at a 1985 White House state dinner), and stroll the palace’s "White Garden," where a happy Harry and Meghan posed for photographers after their engagement.  

Tickets cost about $27 on weekends and weekday mornings ($21 for adults over 60) and $22 during off-peak times ($17 if you're over 60), when bought online

Clarence House

Fans of The Crown, who saw its likeness in the PBS series, will enjoy the home where the queen lived after her marriage to Prince Philip. These days, Prince Charles and Camilla, Duchess of Cornwall, call it home and open its ground floor reception rooms to visitors in August. In the cozy Morning Room, look for two cute ornamental rabbits and a photo of Prince George and Princess Charlotte taken by mom Kate, aka Catherine, Duchess of Cambridge. Book a more comprehensive after-hours guided tour of parts of the buff-colored town house for about $50. It includes the Cornwall Room, where 22 watercolors painted by Prince Charles hang.

Standard tours cost about $15. Book ahead.
