Take the Alewife Red Line to the Harvard Square stop. Exit through the turnstyles and up the stairway that leads to Harvard Yard, and walk into Harvard Yard to the statue of John Harvard. From here, take the path to your left, exit the yard, and veer slightly to the right. The Science Center (a white granite structure with a rock formation in front) will be on your left, and Memorial Hall (a large red brick building with a tall steeple) will be on your right. If Memorial Hall is on your left, you are walking in the wrong direction. This will take you to the intersection of Kirkland and Oxford. Proceed left (westward) down Oxford Street.

Driving Directions

From the North

If you are coming by car from the north, take route 93 or 1 south toward Boston. Take the exit for Storrow Drive-Cambridge. Follow Storrow Drive west for approximately 4 miles. After approximately 2 miles, Storrow Drive becomes Soldiers Field road. You will not notice any change. Stay in the right hand lane in order to avoid the many left hand exits off Storrow Drive until you reach the exit marked Harvard Square/Cambridge. Take the exit and go over the Charles River to the set of lights at Memorial Drive. Go straight ahead through the lights. You will now be on JFK Street and are entering Harvard Square. After you pass the intersection of JFK and Mt Auburn Street, you will come to another set of lights where The Coop is on the left, and Out of Town News and the subway "T" stop are on your right. Go straight (veering slightly to the right) through these lights. You will then approach another fork in the road. Stay to the left of the fork, and then immediately get into the right-hand lane. This will take you onto Massachusetts Avenue, headed north. Go approximately 0.2 tenths of a mile past the Harvard Law School to Everett Street on your right. At the light at Everett Street, turn right and go to the next set of lights at Oxford Street. Take a right onto Oxford Street. Metered parking spaces are on the right.

Take route 3 (South East Expressway) north and follow the above directions for Storrow Drive West.

From the West

Take route 90 (Massachusetts Turnpike) east. Get off the Cambridge/Allston exit (#18) and follow signs for Cambridge, bearing to the right. As you come off of the Turnpike exit, a 10 story hotel is on your right. Begin to move to the left lane as you pass the hotel. There is a traffic light at the corner of the hotel. Go through this light, but be prepared to make a left before the bridge (do not cross over the bridge). You will now be on an entrance ramp leading onto Storrow Drive with very rapid traffic. Follow Storrow Drive for approximately half a mile. Stay in the right hand lane, which will become the Harvard Square/Cambridge exit on your right. Follow the directions given above for coming from the north starting with the sign Take the exit and go over the Charles River.
