点评:Ever plan a trip itinerary, then discover an attraction along the way that you never expected to see--but glad you did. Like the Espada Aqueduct in San Antonio, Texas. How do you miss something that is designated as a National Historic Landmark? Located on Espada Road, north of Mission Espada, it is the oldest Spanish aqueduct in the United States. Built by Franciscan Friars in 1731, it still carries water over Six-Mile Creek on its way to Mission Espada. It was built to supply irrigation water to the lands near Mission Espada. The aqueduct showcases European engineering feats and masonry work. It has withstood major floods and has survived for nearly 300 years. Before the completion of the aqueduct, the Spanish would have used hollowed out logs to carry water over the creek. Once complete, water flowed across the top of the aqueduct in a channel until reunited with the earthen ditch on the other side, then flowed southwardly to Mission Espada and the farmland. Visitors can view the aqueduct from 9 to 4:30 daily. Today, it is part of the San Antonio Mission National Historical Park. In order to distribute water to the missions along the San Antonio River, Franciscan missionaries oversaw the construction of a 15-mile network of seven gravity-flow ditches, dams and at least one aqueduct that irrigated about 3,500 acres of land. The Espada Aqueduct was designated a National Historic Landmark in 1964 and added to the National Register of Historic Places in 1966.
