Across Avenue del Liberator from San Martín Plaza is Plaza Fuerza Aérea Argentina. The focal point of Argentina Air Force Square is a 248 foot tall, standalone clocktower. Torre Monumental was a gift of the British to help commemorate the 100th anniversary of the May Revolution in 1810. The Palladian design by architect Ambrose Macdonald Poynter features red brick between extremes crafted from white Portland stone. On the façade of Tower of the English are reliefs representing Scotland, Wales, Ireland and England. The locals like calling the monument the Argentine Big Ben.
