Back in 2001, one would have thought the Queen City was experiencing a serious case of déjà vu, reveling in the buzz and excitement of the 1901 Pan-American Exposition all over again, when more than eight million people, from local residents to presidents, gathered in Buffalo at the turn of the 20th century to experience the world’s largest and most technologically advanced fair. Now, more than 100 years later, the Pan-Am Exposition site remains a major historical landmark. The 2001 remembrance celebration was such a success that the Buffalo & Erie County Historical Society again invites the city to celebrate the Pan-Am Expo on its 105th anniversary. The event features food, entertainment, docent-led tours of the History Museum and many fun activities for both kids and adults. A Buffalo History Quiz Challenge will test participants on local knowledge, and a San Francisco-style trolley car will run between the museum’s main building and its Resource Center (located around the corner on Forest Ave.), where exhibits from the 1901 exposition and those created for the 2001 centennial will be on display. Among these is a nine-foot-tall model of the Electric Tower, original film footage taken by Thomas Edison’s company and the infamous .32-caliber revolver used by Leon Czolgosz in his shocking assassination of president William McKinley. Despite that morbid touch, this is a family-friendly, community-oriented opportunity to celebrate and remember one of the most electrifying, turbulent times in Buffalo history.

Sunday, June 25 from 12-5pm. Buffalo & Erie County Historical Society, 25 Nottingham Court (873-9644). FREE
