A quarter-century after an anonymous street artist covered the walls of the Swiss Embassy's London car park, the resulting cycle of murals has finally been captured on camera. The documentary, produced for the Swiss broadcaster RTS, offers the first moving images of works that embassy staff have kept behind closed doors since 2000, filmed as the building prepares for an extended renovation.

The centrepiece is the imagery. One pillar shows monkeys on three faces, a second carries officers; around them gather a flamethrower-toting Mickey Mouse, a Mona Lisa under threat, and antennae-capped primates, while the ceiling gives the evening its title: Disco Inferno. The haul runs to about fifteen pieces, or roughly thirty-five if every motif is counted singly. None of it was meant to last — the embassy booked street artists from Britain and Switzerland in December 2000 to dress the garage for a New Generation party, a one-night attempt to look friendlier to younger people in the wake of the late-1990s row over Nazi gold.

Secrecy has been the rule. An embassy is not a gallery, security alone rules out open access, and the Swiss side has long been reluctant to use the work without Banksy's consent, which his representatives at Pest Control have never given. A photographer and Shoreditch street-art tour guide who documented the garage in 2021 was allowed to clear every car so the walls could be recorded properly, and the photographs released with the RTS account are the first to appear in public.

RTS returned to the building in February 2026 with the embassy's cultural team and the photographer. What neither film nor stills can convey, the account notes, is the effect of standing inside the space with the paintings wrapped around the viewer. Whether the garage will look the same after refurbishment is not yet clear, and one mural remains absent from every online source, for reasons the embassy has not explained.
