Academy
All talks, coffee breaks and sandwich lunches take place at the Royal Flemish Academy of Belgium for Sciences and the Arts in Brussels, Belgium. Here is a leaflet (provided by the Academy) with some historical background.
The complete address of the Academy:
Paleis der Academiën / Palais des Académies
Hertogsstraat 1 rue Ducale
1000 Brussel / Bruxelles
The “satellite” option of Google maps has a very high resolution over Brussels, so you can easily identify the Academy in this picture: it is the rectangular building slightly on the north-east of the label.
