It is located in the Cibao Valley, the north-central region of the country, and is divided into 4 municipalities with its capital city being the namesake of La Vega.

The province borders Espaillat and Hermanas Mirabal to the north, Duarte to the east, Monseñor Nouel to the south and Santiago to the west.

The City was reestablished again on March 13, 1813, when the island, after having spent some years under the French rule, was once again under the power of the Spanish Crown, until the unification of Hispaniola in 1822.

On March 4, 1844, La Vega formalized its declaration in favor of independence, and that same day it became the first town in the country to raise the tricolor flag.

Commerce, agriculture and industry gained new momentum with the immigrants from Santo Domingo, Santiago, Moca and other places.

An event that strengthened the economic development of the area was the inauguration of the railway between the port of Las Cañitas (Sánchez) and the city of La Vega, the product of the efforts of the worthy Gregorio Rivas.
