River Pierce Foundation

River Pierce Foundation works to preserve and make known the colonial character of the historic village of San Ygnacio, TX, a significant element of the farms, ranches, cities and towns that make up the Los Caminos del Rio Heritage Corridor of the Lower Rio Grande Valley, Texas. Foundation programs and individual contributions from the private sector support the acquisition, preservation, and creative re-use of historic sites, with special emphasis on the early 19th century sandstone complex of the Trevino-Uribe Ranch, sited on a bluff overlooking the Rio Grande River. Designated a National Historic Landmark by the National Park System in 1998, and as one of the nations most endangered historic sites by the National Trust for Historic Preservation, the fortified complex is one of the few surviving artifacts of Spanish colonial architecture in South Texas.The River Pierce Foundation provides site access to structures in its care to students of architecture, histor
