Sunday classes are held in room 411 of The Harvard Science Center.
Weekday classes are held on the third floor of the Science Center. The Science Center is just
north of Harvard Yard, located at One Oxford St, near the center of
the following map.
Note: Most streets in Cambridge are 'residential sticker required.' There is 2 hour metered parking all along Mass. Ave and Oxford St. If you are willing to come early, there is a chance you will find a spot. Alternatively, there is free, and available, street parking in Somerville, way at the other end of Kirkland, but it means an eight minute walk back to Harvard.
