The meeting will take place at the Philosophy Institute of the Academy of Sciences, located at Jilska 1, 110 00 Prague. The institute can be easily reached by Metro or by tram. The closest metro stop is Narodni Trida (line B of the metro). Once you are out of Narodni Trida stop, you can turn right and cross Narodni, a large avenue, then continue straight ahead. In five minutes you will reach the back of the Philosophy Institute building. The entrance is located at no. 1, in the small plaza on your left. The main door is between two shops of cosmetic/organic products.
Several tram lines also stop at Narodni Trida: 9,3,24,14. The tram stop is just in front of the (only) Metro exit.
