History of the name

The street is named after Spanish General Santiago de Méndez Vigo, who was Governor of Puerto Rico during the early 1840s. The Great Fire of 1841 on January 30 destroyed much of the Villa; of the 700 houses in Mayagüez, only 40 remained. Governor Santiago Méndez Vigo was informed and he immediately headed towards Mayagüez on horseback with a few of his assistants. The governor brings with him 20,000 pesos in silver coins to help the victims of the fire. The Villa of Mayagüez in a gratefulness to the Governor changes the name of the main street to Méndez Vigo. Before the street was called Calle Comercio (Commerce Street).
