Book excerpt: Prince George's County, one of Maryland's most populous counties, has a rich and vibrant history. From agriculture to industry, school life to religious life, trolleys, trains, and tobacco, the people of this area share a distinctive regional heritage and a great pride in the communities they have built. With numerous recognized historic sites, Prince George's County boasts, among others, Mount Calvert, the only structure remaining at the site of the first county seat; Melwood Park and the Magruder House, both visited by George Washington; and His Lordship's Kindness, a five-part Georgian mansion. Other historic buildings were not elegant manors, but functional public facilities. The College Park Airport holds the record as the oldest continuously operating airport in the world, and the Surratt House played a role in the assassination plot of Abraham Lincoln. But the everyday lives of citizens are represented here as well, in the images of early residents, their homes and businesses, of the city services and social events, of elementary school classes and congregations. All can be found within these pages.
