John Bapst High School was dedicated in September 1928 to meet the expanding needs of Roman Catholic education in the Bangor area. The co-educational school operated until 1980, when the diocese closed it due to decreasing enrollment. Since then, it has been a private school known as John Bapst Memorial High School.
The Plymouth Company (1749-1816) managed one of the very early land grants in Maine along the Kennebec River. The maps from the Plymouth Company's collection of records constitute some of the earliest cartographic works of colonial America.
