UPDATE: As of summer 2009, this flea has been revived until at least June, located now at 4th Street between Avenues B and C. For more info, see the comments section below, or read here.
I used to pass the MHC flea market many weekends as I walked my dog from the West Village over to the East (the squirrels in Tompkins Square Park being somewhat more desirable than those in Washington Square). I went down on Saturday just to make sure I had my facts straight about it and . . . in fact, it no longer exists.
I can't substantiate the number, but Shane, who sells used bikes at the Monk Thrift Shop down the street, told me that the church sold the site this spring for $160 million.
Too big a temptation for the Mary Help of Christians, apparently.
The vendors from the market have tried several different sites, but nothing is sticking yet, according to a woman helping Shane sell bikes. Unfortunately, search around the internet and pages that list fleas in New York City still include this one, as well as other defunct markets.
