Zapala was founded on 12 July 1913, and turned into a municipality in 1948. It was (and still is) located around a railway station built by the Buenos Aires Great Southern Railway, a British-owned company taken over by the Ferrocarril General Roca after railway nationalisation in 1948 and, since railway privatisation in 1993, in the hands of Ferrosur Roca. The city is split in two by the railways; on one side there is a commercial district with old buildings, and on the other a modern residential area.
