Kendall Square
314 Main Street
This building, constructed on the former site of a surface parking lot and a single-story bank branch, is largely commercial office space, but is also home to the MIT Press bookstore (which moved from building E38 just down the street) and the MIT Museum (which had formerly been N52, on Mass. Ave.). The new location was chosen for its proximity to Kendall station as the "gateway" to campus for most visitors (who won't be arriving on the 1 bus).
MIT building E38
The "MIT Welcome Center" is located on renovated space in what used to be the MIT Press building — which now has several more floors above it. The welcome center was a new creation; previously there was no central location to orient visitors to campus, and organized tours started from various locations around campus that were closed to the public for the first two years of the pandemic.
Kendall Square proper
Looking east along Main St. towards the Longfellow Bridge. (Note that "formerly West Boston Bridge" is an anachronism: there used to be a low-level draw span called the West Boston Bridge in this general vicinity, which the fixed-spanLongfellow completely replaced. The bridge was built with space for the soon-to-be-constructed subway, as well as streetcar tracks.
Kendall Square
This office building at 255 Main St. has had a variety of tenants over the years — I remember both IBM and Microsoft having space here — but it's new enough and large enough to have only seen minor changes. That glass box on the front is one such change; originally there was no entrance on this side, which conceals an MBTA substation.
MIT building E37
This high-rise at center, plopped on top of an existing, early-20th-century bjuilding, provides new graduate-student housing to partially replace the units lost in the demolition of Eastgate. In the background, 314 Main towers over Kendall/MIT station hreadhouse and six-story 292 Main.
