Stewart Museum, which focuses on the European history of North America from the establishment of New France to the present day, announced Tuesday it is closing its doors for good.The museum’s board of trustees cited “an extremely difficult financial context” coupled with uncertain future prospects as the basis for the decision.While the coronavirus pandemic and the months-long closure of museums impacted the non-profit’s ability to generate revenue through ticket sales and space rentals, it wasn’t the only contributing factor.The museum says it has seen a steady increase in operating costs over the years, as well as a decrease in contributions from various foundations.The board also stated in a news release that it has had difficulty.
