La Boca is a working-class district whose attractions are grouped around the Riachuelo. Grill restaurants and street performers surround Caminito, an alleyway lined with brightly colored sheet metal houses that evoke the early days of neighborhood immigration. Very busy on match days, the Bombonera is the legendary stadium of the Boca Juniors football team. The Museum of Modern Art Fundación Proa offers temporary exhibitions and offers a view of the old docks.
