Things to Do in Brussels in September 2026

September is when Brussels quietly becomes one of the best cities in Europe to be in. The summer crowds have thinned, the temperatures have settled into something more comfortable, and the city shifts into a rhythm that suits it better than July ever did. Galleries reopen after summer closures, festivals move indoors and outdoors in equal measure, and the neighbourhoods around Ixelles and the Sablon come back to life in the particular way they do when the academic year starts and the city fills up again.

Here is what is happening this month, from the Louise quarter and across the city.

Brussels Art Week — 10 to 13 September

The biggest cultural event of the Brussels autumn arrives this week. Brussels Art Week brings together eighty venues across the city, galleries, foundations, public institutions and artist studios, in a four-day celebration of the contemporary art scene. Many of the venues are free to enter. The ones that are not are generally worth paying for.

The programme is organised around three geographic areas across three days. On Saturday 12 September, the focus shifts to the centre of Brussels. On Sunday 13 September, the south of the city takes over, which means Ixelles, the area immediately around Made in Louise, becomes the territory of the day. The galleries, studios and foundations in the neighbourhood that tend to be visited separately across a year are all active simultaneously on the same afternoon.

The opening evening on 10 September gathers the Brussels art world in one place for the traditional vernissage. If you are in the city that Wednesday, it is worth looking up what is on near the hotel. More information on the official Brussels Art Week website.

Genesis — Sound and Light at Notre-Dame du Sablon | 12 September to 25 October

From 12 September through to 25 October, a new immersive show arrives in Brussels inside the Gothic church of Notre-Dame du Sablon. Genesis, produced by Eonarium Experiences, uses sound and light to tell the story of Creation across the seven days of the Book of Genesis, working with the architectural heritage of a church whose origins date to 1308.

The result is the kind of experience that is only possible in a building of this age and this scale. The nave, the vaulted ceilings, the stained glass all become part of the composition. It runs for six weeks, which gives time to plan rather than rush. Tickets and booking are available on the Eonarium website.

The Sablon is fifteen minutes from Made in Louise on foot, through the Royal Quarter and past the Palais de Justice a walk that is worth doing slowly in September when the city is at its most pleasant. The neighbourhood itself, with its antique dealers, chocolatiers and gallery spaces, adds a full afternoon around the show.

Marni Jazz Festival — 10 to 19 September | Place Flagey

The Théâtre Marni, a few minutes from Place Flagey, hosts its annual jazz festival from 10 to 19 September. The programme blends jazz with other musical genres in an intimate setting, the kind of concert experience that the Marni does particularly well, with a room small enough that the distance between the audience and the musicians rarely feels significant.

Alongside the concerts, a black-and-white drawing exhibition by Alain Dauchot, titled Jazz, Portraits Clashés, runs through the end of October. It is the kind of programme that rewards coming back more than once.

Flagey is ten minutes from the hotel on foot, through the Châtelain quarter. The combination of the festival and the square on a September evening the ponds lit at dusk, the Art Deco building of the Flagey concert hall across the water is one of the better things Brussels does this time of year.

Sablon Design Market — 13 to 15 September | Place du Grand Sablon

Running alongside Brussels Art Week on the same weekend, the Sablon Design Market takes over the Place du Grand Sablon from 13 to 15 September. Exhibitors from Belgium and France bring vintage leather goods, mid-century furniture and luxury accessories to a square that is already one of the more handsome in Brussels.

The timing is useful, the Sablon is a natural extension of a day that starts with Art Week in Ixelles on Sunday afternoon. The Genesis show at Notre-Dame du Sablon runs on the same weekend. The three events form a coherent itinerary without requiring much planning.

Our September Pick

Baci is a modern restaurant offering Italian cooking from antipasti and pizza through to more traditional dishes, linguine alle vongole among them. Some of the specialities have been revisited to give familiar things a slightly different finish. Worth knowing about for an evening in the neighbourhood.
