By car: Note that the visitor car parks are off campus (though within easy walking distance from the department). The most convenient for you is the "South Car Park" off Edgbaston Park Road. Set your SatNav to "B152TT" or to "Barber Institute" to get there but I recommend that you familiarise with the campus map as well. It costs £1 to park your car all day. It shouldn't happen but if you find the South Car Park full then I suggest you carry on to the "North Car Park", off Pritchatts Road. To get there, continue on Edgbaston Park Road past the East Gate of the University and turn left into Pritchatts Road.
If you need to drive onto the campus then contact the local organisers so a permit can be arranged for you.
