Bangor’s Great Fire of 1911 burned more than 55 acres of land, including 267 homes and more than 100 business buildings in a single afternoon. Bangor High School geography students from have created historical atlases about the fire and other events in Bangor’s history and have put them on the Community Atlas Web site. The students will share their project and demonstrate the Web site at 1-3 p.m. today, at the Bangor Museum and Center for History, 6 State St.. After the Web site demonstration, Mike Pullen of WBRC Architects-Engineers will present the story of the fire and the city’s recovery. He will give a PowerPoint presentation and walking tour of the downtown area affected by the fire. The program is related to the Bangor Museum’s new, permanent exhibit, “Crossing the Bridge: Bangor in the Twentieth Century,” at 6 State St. Also on exhibit is “In Our Own Words: Bangor Rotary History Gallery,” featuring the oral histories of many of Bangor’s community leaders and an interactive digital exhibit, using the oral histories. The Bangor Noon Rotary Club and the Bangor Area Breakfast Rotary Club joined forces to fund and help create the exhibit. Admission to the program and exhibits are free.
