Ancienne Belgique, known to locals simply as “AB,” is a concert hall in the historic heart of Brussels, Belgium, standing on Boulevard Anspach. The site’s music-hall history stretches back to the early 1900s, but the venue took on its current name and identity in 1931, when 22-year-old Liège businessman Georges Mathonet took over the building and began booking major touring acts.
After a mid-20th-century golden age hosting stars like Jacques Brel and Édith Piaf, financial troubles forced AB to close its doors in 1971. The Belgian state bought the building, and following a string of renovations it reopened as a dedicated home for contemporary live music. Today AB operates as one of Belgium’s premier concert venues, built around two very differently sized rooms — the big Main Hall and the compact AB Club — that let it book everything from arena-bound headliners to artists just breaking through.
Quick Answer
Ancienne Belgique (AB) has two performance spaces. The Main Hall is the big room, holding up to 2,000 people standing (it can also be reconfigured for smaller all-seated or theatre-style shows down to around 500). The AB Club, AB’s smaller room, holds up to 280 people and is used mainly for emerging artists and club-style nights.
AB’s Capacity: Main Hall vs. AB Club
The Main Hall is AB’s flagship room: roughly 440 square meters with two levels of galleries, a preserved red interior, and a layout that can flex between a 2,000-person standing show and smaller seated or “ballroom” configurations in the 500-to-1,350 range. It’s this room’s acoustics — regularly ranked among the best in Europe — that gave AB its reputation as a serious listening room as well as a party venue.
The AB Club is a separate, sound-insulated room on the first floor, about 170 square meters, with a listed capacity of roughly 100 to 280 guests depending on setup. It’s where AB books developing acts, late-night club sessions, and the kind of intimate shows that don’t need the Main Hall’s scale — including the mid-1980s New Beat club nights that helped shape Belgian dance music.
Because both rooms are rented and booked at different sizes depending on the event, exact capacity for any given show can vary slightly from the numbers above — the venue’s own room-hire page breaks down the current configurations in detail.
A Storied Stage in the Heart of Brussels
The building at Boulevard Anspach 110 has entertainment roots going back further than most venues its size. In 1906 it opened as the Vieux Düsseldorf, a roughly 1,500-seat hall for orchestras and variety shows, before passing through several identities as a dance hall. Georges Mathonet’s 1931 takeover is what launched the “Ancienne Belgique” era proper, and over the following decades the hall became a regular stop for major French-language stars, including Jacques Brel — who famously played there in January 1955 — along with Édith Piaf and Charles Trenet. From 1954 to 1964, AB even operated in partnership with Bruno Coquatrix, the longtime manager of Paris’s Olympia.
Rising costs and tightening safety regulations forced AB to close in 1971. The Belgian state purchased the building in 1977 and handed it to the Flemish cultural community, which reopened it as a contemporary concert hall from 1979 under promoter Paul Ambach, booking acts like Leonard Cohen and Kraftwerk. A licensing dispute over noise forced another renovation in the early 1980s, and AB reopened on December 23, 1983. A far larger rebuild followed: AB relocated temporarily to the Luna Theatre from 1986 to 1996 while the Boulevard Anspach building was expanded and modernized, reopening in 1996 with the larger, technologically updated Main Hall and Club layout the venue still uses today. AB was recognized as an official Institution of the Flemish Community in 2008.
Landmark Shows and Live Recordings
AB’s stage has hosted no shortage of memorable, even chaotic, nights. Suicide’s confrontational 1978 performance opening for Elvis Costello was captured and later released as a live album, while The Cure’s 1982 show ended in an on-stage dispute among band members. The venue’s acoustics and atmosphere have also made it a favorite recording location, with artists such as Iggy Pop (Live at the Avenue B, taped in 1999), Kings of Leon (Day Old Belgian Blues, 2004), and King Gizzard & the Lizard Wizard (Live at Ancienne Belgique / Live in Brussels ’19) releasing official live albums recorded at the venue.
Visiting AB: Doors, Tickets & Getting There
Ticket prices at AB scale with the room and the act — Main Hall shows with international touring artists cost more than AB Club dates with developing acts, and AB also sells drink tokens in bundles at the venue. For most concerts, doors open in the evening ahead of a show that typically wraps by around 10:30 p.m., timed to Brussels’ public transit; AB’s ticket shop also keeps separate daytime hours for walk-up sales and will-call. Because exact showtimes, doors, and current prices change event by event, check AB’s official website and its ticket info page before you go — both are the canonical source for a given show’s capacity configuration, pricing, and timing.
AB sits right on Boulevard Anspach in central Brussels, within easy walking distance of Brussels-Central train station, making it one of the more transit-friendly venues in the city for an evening show.
