Following their nuptials at St. George's Chapel in Windsor, England, the newlyweds will greet well-wishers throughout the town in their Ascot Landau horse-drawn carriage before returning to Windsor Castle for their multiple celebrations.
As preparations are underway, ET is breaking down everything you need to know about the royal wedding receptions and after-party.
1. Wedding Luncheon
About 600 people are invited to the post-ceremony luncheon reception, which will be hosted by Queen Elizabeth II at St. George's Hall at Windsor Castle. “Windsor is a very special place for Prince Harry, and he and Ms. Markle have regularly spent time there during the last year,” a spokesperson for Kensington Palace previously shared.
2. First Reception
Following the luncheon, Meghan and Harry will invite guests to their reception in the Waterloo Chamber, St. George's Hall and the Grand Reception Room that is in the castle. These rooms have always been used by the royal family for big celebrations. St. George's Hall is the largest room in the castle and is decorated with shields celebrating the Order of the Garter.
3. Food Being Served
Guests have much to look forward to at the luncheon and reception. Pastry chef Claire Ptak is baking a cake that's perfect for spring! Kensington Palace revealed the dessert will have a lemon elderflower flavor and be "covered with buttercream and decorated with fresh flowers."
Royal Chef Mark Flanagan and his team are also whipping up a slew of tasty foods for the big day. "The couple have been very involved in every detail of it," said Flanagan -- who reveals that much of the produce used in the kitchens is seasonally-led, sourced from farms around the UK and off The Queen's Estate at Windsor -- per Kensington Palace.
We dropped in on the Kitchens at Windsor Castle, who will shortly begin final preparations for the #RoyalWedding.
Pastry Chef Selwyn Stoby will be working on the day of the wedding and prepare chocolate truffles – a favorite dessert served at receptions throughout the year at Windsor Castle. The team will also be making bite-sized Crème brûlée, biscuits with mango pannacotta topping and yellow macaroons.
The party doesn't stop there! Around 200 guests have also been invited to a private reception hosted by Prince Charles at Frogmore House. This location, about a mile from Windsor Castle, was the same one that Meghan and Harry used to take their engagement photos.
At this more intimate affair, special musical guests are expected to attend!
