Directions & Parking

The Harvard Law School has written instructions for travel by car, but we recommend taking public transportation. Langdell Hall is a ten minute walk from the Harvard Square Red Line T stop and fifteen minutes from the Porter Square commuter rail. Massachusetts Avenue is serviced by the #1, #77, and #96 bus lines. For more detailed information regarding public transportation, see the Massachusetts Bay Transportation Authority (MBTA) website.

Most on-street parking in the area is reserved for city residents with Cambridge vehicle registrations. On-street metered parking in Harvard Square is scarce.

Visitors may park on campus by purchasing a permit through the Harvard Campus Services website. The weekday daily visitor’s rate is $17 per permit. Parking can be reserved up to a week in advance of your visit. Please reserve parking for your visit as soon as possible as parking spaces close to the Law School fill up quickly during the school year.

Purchase a daily visitor parking permit and then follow the instructions below.

  • Click “Visitor” at the bottom of the Daily Visitor Parking Permits Online Purchase System page.
  • Enter your log-in information if you have used the system before, or register if you have not.
