Parts of this plaza, right downtown and the oldest in town, date from 1767. The streets surrounding it are cobblestoned and lined with ancient oaks where you can escape the sun. For details about the historic buildings throughout downtown, pick up a copy of the brochure Heritage Walking Tour of Historic Laredo at the CVB or at area hotels.
Nearby streets are interesting for the traditional shops catering to day-tripping Mexicans. Step behind the La Posada Hotel for views of the fortified border area, the trickle of the Rio Grande and the omnipresent huge Mexican flag.
