Pi Bench
Charles River Esplanade Pi Plaque, 334 Back St, Boston, MA 02116, USA
About
A bench along the Charles River Esplanade with a small bronze plaque engraved with the first 100+ digits of pi... no name, no dedication, just numbers, donated anonymously (MIT is right across the river, draw your own conclusions). Take the Fairfield Street Footbridge onto the Esplanade, then head down toward the water near the trees to find it.
