“The event manager at Syon Park, a popular wedding venue west of London where we filmed Lady Danbury’s ball in Season 2, tells us that many of their brides mention the show and ask for the flower arrangements to be like Bridgerton,” said Tony Hood, the supervising location manager for “Bridgerton.” He said he has seen viewers of the show regularly visiting places like the Old Royal Naval College in London, the site of Penelope and Colin’s wedding in Season 3 and the city of Bath, where several scenes have been filmed.
