Rodrigo Pacheco, 3rd Marquess of Cerralvo

Don Rodrigo Pacheco y Osorio de Toledo, 3rd Marquess of Cerralvo (Spanish: Rodrigo Pacheco y Osorio, tercer Marqués de Cerralvo) (c. 1565, Spain – June, 1652, Madrid) was a Spanish nobleman, inquisitor of Valladolid, and viceroy of New Spain.

When the rioting and disorders involving the previous viceroy, Diego Carrillo de Mendoza, 1st Marquess of Gelves, and the archbishop of Mexico, Juan Pérez de la Serna came to the attention of King Philip IV of Spain, he chose Pacheco y Osorio to investigate the causes and take charge of the government.

On December 15, 1628 Dutch Admiral Piet Hein captured a Spanish fleet in the straits between Florida and the Bahamas.

Later in his administration, Dutch corsairs occupied the city of Campeche (April 17, 1633), but were driven out by 200 militiamen under the command of Captain Francisco Maldonado.

After major flooding in 1607, there was a large-scale project to drain water from the city via a combination of an open drainage ditch and tunnels.

He restored and reinforced the walls surrounding the city and began some other minor projects to complete the earlier plans of the engineer Adrian Boot.

On May 19, 1630, the viceroy ordered the capital moved to Tacubaya, nearby but on higher ground, pending an open discussion in the guilds of the city.

By 1632 the Huehuetoca canal had finally been completed and the Calzada de San Cristóbal, atop a wall surrounding the city that served as a dike, had been renovated.
