In Harry Potter and the Deathly Hallows – Part 1, Bill Weasley and Fleur Delacour marry at the Burrow. The Weasley family home hosts the wedding before the celebration is attacked by Death Eaters.
The Burrow is a magically expanded house near Ottery St Catchpole and is closely associated with the Weasley family. Its warm, crowded setting contrasts with the increasingly dangerous world outside the protective enchantments.
After the attack, Harry, Ron and Hermione leave immediately to begin their hunt for Voldemort’s Horcruxes. Shell Cottage, another Weasley-related location, becomes important later, but it is Bill and Fleur’s home rather than their wedding venue.
