On Monday 15 the Workshop will be held at the Fondazione Bruno Kessler in Povo. On Tuesday 16 and Wednesday 17 it will take place at the Faculty of Law of the University of Trento, which is situated in the historic center of the town, at walking distance from most of the hotels and restaurants. The entrance for the participants of the workshop is in via Antonio Rosmini 27. A registration desk will be present in the Foyer next to the main entrance. The seminar room is "Aula 2" (lecture room n.2), first floor, on the left of the Foyer.
The social dinner will be take place at the Museum of Science (MUSE), at walking distance (10 min) from the site of the workshop. The dinner is free for registered participants. The cost for accompanying persons is 40 euro.
