Atlanta is the capital of Georgia and a center for civil rights history, music, and film. The Martin Luther King Jr. National Historical Park preserves the birth home, church, and tomb of Dr. King in the Sweet Auburn neighborhood, the National Center for Civil and Human Rights tells the story of the civil rights movement downtown, and the Atlanta BeltLine turns former rail corridors into trails, parks, and public art. Piedmont Park offers green space in Midtown, the High Museum of Art anchors the Woodruff Arts Center, and the Georgia Aquarium is one of the largest aquariums in the world.
