The Swingathon festival, was held from July 17 to 20 in the village of Allington in Lincolnshire town, home to just 897 residents. Each attendee reportedly paid around US$250 to join the controversial gathering.

Now in its fifth edition, Swingathon caters to individuals and couples embracing open relationships, including members of the LGBTQ+ community, The Sun reported.

The event featured glamping accommodations, live music, DJ sets, and workshops on sexual wellness.

Despite assurances from organizers about improved soundproofing and hygiene, locals were outraged.

Some described being “tortured by loud moans” throughout the weekend and slammed the event as a “shady activity” that tarnished the village’s image, New York Post reported.

“Allington is now being called the swingers’ capital of the U.K.,” one elderly resident said. “Most of us here are older and were shocked that our peaceful village was chosen for this.”

Event DJ Kerry Voellner said the organizers had made efforts to improve conditions compared to previous years. “We’ve made soundproofing better and are keeping everything as clean and hygienic as possible,” he said.

Organizer Matt Cole defended the event, claiming it caused no disruption. “It’s hard to hear anything unless you’re actually inside the venue,” he said.

Organizers provided approximately 4,000 condoms and offered free STD testing kits, with about 50% of attendees reportedly using them.

Despite community backlash, organizers expect attendance to double next year.

Founded in 2020, Swingathon now includes music, workshops, and stalls, welcoming people from the LGBTQ+ and kink communities. But some locals remain opposed, calling the event “seedy” and claiming it is unwelcome in their quiet rural community.
