Venue Information

Parking is incredibly limited at Greentown Labs. We encourage attendees to consider taking advantage of public transportation. We’re a short walk from the newly opened Union Square station, as well as 1 mile away from the Harvard MBTA station. Union Square in Somerville is also easily accessible via the #86 and #91 MBTA buses. We offer indoor bike parking on-site and the closest Bluebikes stations are at Dane St., Conway Park and Union Square.
