The Historical Society of the Tonawandas sponsors an Flea Market as a fund raiser for its two museum sites, the former New York Central Train Station, and the Benjamin Long Homestead. The location is Clinton Park, Tonawanda, NY. Clinton Park was selected many years ago as a shady and accessible venue. It is about four blocks from the other Canal Fest events in downtown North Tonawanda and only three blocks from the Museum in Tonawanda. The Flea Market is a two-day event with overnight security for vendors; the Canal Fest runs 8 days. Map. The new Gazebo.
