One of the most beautiful squares in Spain. It was built in Baroque style according to the plans of Alberto Churriguera. On the north side is the City Hall, a Baroque building that has five granite arches and a steeple decorated with allegoric figures. In its decoration several medallions stand out, including those of Charles I, Alfonso XI, Ferdinand VI, Cervantes and St. Theresa. The façades of the buildings are three storeys high, with semicircular arches and balustrades. Today, this square is one of the most lively and popular places in Salamanca.
