Ten checked events and festivals in Hauts-de-France this weekend, August 8-9, 2026, from the 48 Heures Country Rétro in Liévin to stargazing in Ermenonville.
Events and festivals in Hauts-de-France this weekend, August 8-9, 2026: ten checked picks running from the Opal Coast to the Somme, by way of the Oise. A retro country weekend takes over Liévin, a stargazing night settles into Ermenonville's 18th-century park, and the Hardelot Festival plays its closing concerts. Our pick of the weekend goes to the 48 Heures Country Rétro in Liévin, a full immersion in 1950s America a few miles from the old mining basin. Looking for something free and outdoors instead? Beauvais Cathedral lights up every night through late September.
Stargazing Night in Ermenonville: three evenings under the sky
Ermenonville's Jean-Jacques Rousseau Park, an 18th-century landscaped garden in the Oise, hosts the French Astronomy Association's national Nuits des Étoiles from August 7 to 9. Expect an inflatable planetarium, guided viewing through telescopes and binoculars led by amateur astronomers, and science and art workshops open to all ages. The park's dark skies, well away from the light pollution of Paris or Senlis, make it a solid spot to catch Saturn, the Moon or summer star clusters. Free and family-friendly, best enjoyed after dark rather than during the day. The full schedule lists the observation slots.
48 Heures Country Rétro in Liévin: boots, denim and Route 66
The Chalet Brand in Liévin turns into 1950s America from August 7 to 9. Local charity Motards de l'Espoir runs country and rockabilly concerts, dance workshops led by six instructors, and a vintage car and motorcycle show. Three days built for fans of electric guitars and old Cadillacs, but easy to enjoy even if that's not usually your scene, right in the heart of the former mining basin. The event page lists all three days of concerts.
BB Rock in Albert: ten emerging bands for a first edition
On August 8, local association La Fabrik Vivante launches the first edition of BB Rock, an open-air, community-run festival just outside Albert in the Somme. Ten emerging regional bands take the stage across rock, pop, psych, soul, grunge and garage — a deliberately wide net, built for discovery rather than headliners. Showing up for a first edition means betting on what the festival will become. The event page has the full band lineup and set times.
Hardelot Festival: closing weekend of classical and jazz
Now past its 45th edition, the Hardelot Festival brings classical and jazz concerts each summer to some of the Opal Coast's best-loved venues: the Hôtel du Parc, the Église Saint-Augustin, and Neufchâtel-Hardelot's Elizabethan theatre. The weekend of August 8-9 marks the close of this year's edition, which opened in late July. The closing weekend programme brings the three venues together for one last run of concerts.
Les Estivales Musicales de Hardelot: a free concert every Saturday
Every Saturday of the summer, Neufchâtel-Hardelot's Place de la Concorde hosts a free open-air concert organised by NH Famille Sport Nature. On August 8, the lineup runs through pop-rock, French variety, world music, blues and tribute acts, starting at 6.30pm. No ticket, no booking — just an early-evening show for holidaymakers and locals alike, easy to combine with the last Hardelot Festival concerts a short walk away. This week's lineup is updated every Saturday.
Les Malins Plaisirs in Montreuil-sur-Mer: theatre made on site
Through August 16, Montreuil-sur-Mer and the villages of the Montreuillois host Les Malins Plaisirs, a theatre festival built around residencies: directors, actors, musicians and costume designers create new shows specifically for the heritage sites that host them — ramparts, courtyards, halls — rather than adapting existing work to the venue. The weekend of August 8-9 falls right in the middle of this two-week residency. The performance schedule lists times and locations, which shift from day to day.
Beauvais, the Infinite Cathedral: a free light show every night
On the square in front of Saint-Pierre Cathedral, home to the tallest Gothic choir in the world, the Skertzo agency projects a 30-minute sound-and-light show every night through late September. The poetic, musical narration retells the unfinished history of a cathedral that's been under construction since the Middle Ages. Free, family-friendly, no booking required — just take a seat on the square after dark, on the 8th as much as the 9th. Screening times shift slightly through the season.
Amiens' Hortillonnages: an open-air museum on the water
Since 2010, the International Garden Festival has turned the hortillonnages of Amiens — floating gardens shaped by hand since antiquity — into a trail of some fifty contemporary creations. Gardens, installations and site-specific works are built to blend into the landscape rather than dominate it, and can be explored on foot or by boat depending on the entry point. Mid-August, with dense summer growth and low evening light, is one of the better times to visit. Visit details are worth checking beforehand, as some access points require booking.
Video Mapping Festival in Lille: Old Lille's facades come alive
Run by the association Rencontres Audiovisuelles, the Video Mapping Festival offers a self-guided night trail of video-mapping works projected onto the facades of Lille's city centre and Old Town, running through late October. The event, unique of its kind in France, also includes an international competition and a creative residency. Unlike a single-weekend festival, the trail can be walked whenever the sun goes down — a free, self-paced way to spend an August evening. The trail map is available online.
Artpenteurs in French Flanders: monumental works in open countryside
Launched in 2024 by Cœur de Flandre Agglo, Artpenteurs is an open-air contemporary art trail running through the French Flanders countryside, from Steenvoorde to Bailleul, until late October. About ten monumental, temporary works by land-art specialists are set into notable natural sites: hills, meadows, woodland edges. The trail works on foot or by bike, over a few hours or split across several outings. A solid pick for the weekend of August 8-9 if the weather holds. The full trail lists every village along the way.

Ten confirmed events, two more worth tracking: enough to fill the weekend of August 8-9, 2026 in Hauts-de-France, from the Opal Coast to French Flanders. For more events and festivals across the rest of France, check the full weekend agenda.
