One of my favorite things about Cambridge, and Harvard Square in particular, is how many decades, centuries actually, are commemorated here.
From Colonial times to the recent past - there are buildings, monuments, plaques and more memorializing people, places and events from Cambridge's past.
Walk down any block and you're likely to come across the juxtaposition of Cambridge then and Cambridge now.
Here are a couple I spotted recently:
The first school house in Cambridge in 1646 was here on what is now Holyoke Street in Harvard Square. The street was called Crooked Lane in the 1600s.
Today, where the school house once stood is Looks, a women's boutique - one of several you'll find in Harvard Square.
On the other side of the square, in the Cambridge Common, this plaque marks the site of a Revolutionary War encampment (complete with a 21st century water bottle littering the lawn)
Now, the site of a playground for Cambridge kids.
Take a walk around Cambridge and stroll through the centuries.
