Rosich y Más is best remembered for what he did for Ponce as a non-citizen more than what did as mayor. He is remembered for having conceptualized, in 1877 the creation of a Fair in Ponce modeled after the Paris Fair of 1855 and, subsequently, in 1878, the main city square and streets were electrified, just like Paris, on the first day of the fair. The great fair in Ponce took place in 1882 and Parque de Bombas was built then and left as a legacy until today.
