Brockwell Under Siege

Oscar-winning actor Sir Mark Rylance has publicly criticized a series of large-scale summer music festivals held in south London’s Brockwell Park, claiming the events transform the beloved green space into something akin to a “prison camp.”

Each summer, Brockwell Live draws over 300,000 festivalgoers with pop-heavy lineups featuring artists such as Kesha, Eurovision winner Loreen, and ex-Little Mix star Jade Thirlwall. But as the music booms, a battle is growing louder among concerned residents and campaigners who say the park — and the wildlife that calls it home — is paying the price.

Rylance, a local resident and environmental advocate, is among the high-profile voices backing a campaign to legally challenge Lambeth Council’s decision to allow the festivals to proceed without formal planning permission. The actor has warned of long-term ecological consequences, arguing that the infrastructure required for the events is scarring the park’s landscape.

“The imposition of high steel walls for Brockwell Live every summer destroys the park for weeks and harms the grass, trees and plant life for months if not for ever. It turns it into a prison camp,” said Rylance.

His stance aligns with the Protect Brockwell Park group, which has raised over £31,000 and engaged environmental lawyers in an effort to halt this year’s events. Their legal letter to the council may lead to a full judicial review.

The campaign is calling for a break in the festivals to allow the park to recover, more community input on future events, and reparations from organizers Superstruct, a major player in the festival industry.

In response, Lambeth Council maintains that only low-sensitivity areas are used for the events and denies any lasting ecological damage. Officials say income from the festivals helps fund diversity and park improvement projects, including a reported £500,000 annual investment in Brockwell Park’s upkeep.

Still, for many residents, that reassurance rings hollow. With steel fences dividing the green space and heavy foot traffic compacting soil, locals say the park's core purpose — as a shared sanctuary for people and nature—is being lost in the noise.

As festival season approaches, the battle over Brockwell is set to intensify — pitting cultural celebration against conservation, and star power against city policy.
