Driving and Park
If you are new to this area, we strongly recommend "park & ride" at the Alewife station of Red line T (subway). It is only 3 stations away from Harvard sq. station. (day parking for 5 dollars).   

If you prefer parking near the symposium location, there are street parking spots on the Massachusetts ave., Garden st., Oxford st. Please kindly be advised that the roads are very complex to drive and there are  very limited spots for parking with a strict time limit (usually 2 hours).

Or you may want to check Havard University general parking information page.
