When Franklin Roosevelt was at Harvard in the very early 1900s, he rented rooms at what is now the university's Adams House dormitory. The 32nd president's old suite has been restored to its period-piece glory, and tours are available. Unfortunately, they are largely open only to Harvard students, alumni, or affiliates; and they have to be booked at least two weeks in advance. So perhaps spend Friday arranging a tour of how blue-blooded collegians lived 110 years ago.

I.M. Pei designed the Columbia Point library and museum dedicated to the nation's 35th president, a Brookline native and scion of an old Boston-based political clan. It opened in 1979 and was rededicated in 1993. It has everything JFK-related, including special exhibits and programs. Consult its website for hours and fees.

The house where the 35th president was born and raised is a national park and therefore free. Tours should be scheduled at least two weeks in advance, however. Added bonus of doing so nowadays? 2017 marks the centennial of JFK's birth, so his birthplace is holding special events throughout the year.

The national park that encompasses the birthplaces of John Adams and John Quincy Adams is only partially open until Feb. 28. The visitors center and the attendant bookstore are, but the actual homes where the second and sixth presidents were born are not (still, you can check out the exteriors).

John Adams and John Quincy Adams (and their wives) are entombed in the United First Parish Church; and tours are available during the warmer months. The Greek Revival church itself is pretty impressive, one of the finest of its architectural kind in the U.S.

Located within Forbes Library, this repository of the 30th president's papers and sundry memorabilia is the only presidential library located in a public counterpart. Why in Northampton? Because Coolidge was mayor there before he became Massachusetts governor, vice president, and president; and he then ran out the clock in the city post-White House. The library is closed Fridays, but open much of the rest of the week.
