Through its history, both the site and name of this city has changed. Starting as San Buenaventura de Colorados in the seventeenth century, then, Nuestra Señora de Guadalupe in the eighteenth century, and finally, San Buenaventura in the nineteenth century, this town has changed its physiognomy gradually.

Witnesses to these changes are the Municipal Palace, the church tower, the old cantera stone mill, and the Melchor Ocampo Mutualist Society building, all from the first decade of the twentieth century.

With its municipal seat located 21 Km. (13 miles) to the northeast of Monclova, the sanbonenses de not forget to entertain their visitors with a full glass, machacado (dried beef and eggs) and a delicious nut roll.

An important event worth attending is the well-known Patron Saint Fair on July 14th where the fun is big with bull running, rodeos, dances, and fireworks.
