San Antonio was founded in 1718. By 1730, the viceroy of New Spain had
issued orders to map plazas, squares, and parks for the Canary Islanders
who would be arriving in 1731. The plazas with their markets became the
centers for business and entertainment. The first square was Plaza de
Armas (Military Plaza); when the islanders arrived, they marked off the
Plaza de las Islas (Main Plaza). Before the Civil War, Alamo Plaza was
the center of commerce. As San Antonio grew, the markets needed to
relocate. The construction of Municipal Market began in 1899. This
market house, built in Paschal Square, was demolished in the 1930s, but
the Municipal Market Annex, constructed in the 1920s, survived. The
annex buildings would become El Mercado and Centro de Artes. In the
1970s, a permanent building for the farmers market was built in Hay
Market Plaza. Today, these buildings, along with the historic buildings
in the area, are known as Market Square.
