International Trade Union House,
Koning Albert II-laan, Nr 5
The International Auditorium conference centre is located in the heart of Brussels, within walking distance of the Place Rogier metro station, the Gare du Nord railway station, and Rogier and Manhattan car parks.
Gare du Nord / Brussel Noord is the closest train station, being only a short 6 minute walk from the International Auditorium.
If you come by train from the UK or France, you'll arrive in Bruxelles-Midi/Brussels Midi/Zuidstation with the Thalys or Eurostar, and there is an express train to North Station every 15 minutes.
Leave Brussels North train Station in the South direction (CCN). It is about 6 mins (500 meters) walk to the International Auditorium if you take the back exit into Noordplein/Koolbrandersstraat, and walk it out (200 meters) until you come in the Koning Albert II-laan, where you turn left and continue for another 300 meters. It may be a good idea to have a quick look at a Maps app before you start walking, but you can really do it in 6 minutes if you take the shortest route.
From the Airport:
The easiest way is to take the airport train which usually takes less than 20 mins to Gare du Nord/Noordstation/Brussels North Railway Station. The train costs something like 10 euro per person, cheaper than a taxi or even an Uber.
Because the International Auditorium is situated near the Brussels inner Ring, it is very easily reachable by car (if the tunnels are open). When entering Brussels follow Direction: "Brussels Centre", exit Rogier. Parking facilities: "Place Rogier (Interparking)" and various other car parkings in that area.
The International Auditorium has no separate parking. There are 5 public parking spaces in the immediate area, of which the Parking Rogier (see the Interparking Web site of Parking Rogier) and Parking Botanique (see the Interparking Web site of Botanique) are the closest.
