How to find the CCA 2007 conference venue: 1. The conference venue for CCA 2007 is College Santa Chiara (Auditorium), see http://www.unisi.it/santachiara/home.html 2. If you arrive by plane in Florence, take the shuttle bus to the main station S. Maria Novella. You can reach this station also by train from Pisa airport. 3. There is then a bus from the train station to Siena. However, it starts not exactly from the station, but from Via S. Caterina da Siena (S. Caterina da Siena Street). To find it, leave the station from the exit of Via Alamanni (Alamanni Street). Cross the street and then turn left, follow Alamanni street and after some meters turn right at the first corner. The bus station will appear then on your right side after few meters. 4. You can take any bus to Siena. You do not have to book the ticket in advance. The last bus leaves at 20:15. 5. Do not leave the bus too early. Get off at the final destination Piazza La Lizza (La Lizza Square) (the same station is also denoted by Via Tozzi). This is still quite far away from the conference venue. 6. Take a look at the map on the CCA 2007 web page http://cca-net.de/cca2007/ for further orientation (the Piazza La Lizza is above the Stadio Comunale on the map).
