After the end of the Venetian Republic Verona went to Austria with the Treaty of Campo Formio in 1797; the previous one, anti-French uprising of the Verona at Easter was bloodily suppressed. Under Austrian rule, the city was part of the northern Italian Quadrilateral (it .: Quadrilatero), which was to defend the Austrian possessions in Italy in Peschiera, Mantova ( Mantua), Legnago and Verona built 1815th. The expansion was made by Austrian 1833-1866 pioneers designed by the engineer General Franz Scholl. 1866 Verona came as a result of the German War to the Kingdom of Italy." Wikipedia (
