One last hang at the Pit in Harvard Square

The organizers of Pit-A-Palooza are aware of the irony. They’re putting on an organized, permitted event to celebrate the impending demise of Harvard Square’s longtime home of anarchy, spontaneity and youth culture: the Pit.

The sunken area behind the entrance to the Harvard MBTA station was originally designed with the intent of showcasing street performers — and at times it did. But within months of being unveiled as part of the 1982 Red Line extension, the Pit became a gathering place for punks and outcasts. With renovations about to replace the Pit with a plaza, a group of self-described “Pit Rats” are gathering for a reunion and celebration called Pit-A-Palooza on June 25.
