Auditoire de Calvin
The Church is the "Auditoire de Calvin " which is no. 1, Place de la Taconnerie. It is situated right next to St Pierre Cathedral in the Old Town. If you are standing at the main entrance to the Cathedral, you need only walk round to the right of the building to see the Auditoire facing you from across a small road.
If you are travelling by car you should use the St Antoine Car Park, which is well signposted when you get close to the Old Town.
When you leave the car park on foot you should head up the hill into the oldest part of town and look for the Cathedral Spire.
Coming by bus you should take the 3 or the 5, both of which pass by the main train station at Cornavin, and get off at the "Palais Eynard" stop. From there head up the hill and you will come to an open space called the Place Bourg de Four. From here continue on up the hill. The first turn on the right (Place de la Taconnerie) will lead you to the Auditoire. The walk will take around 5 minutes.
