Treviño

For people with the surname, see Treviño (name).Treviño is the capital of the municipality Condado de Treviño, province of Burgos, in the autonomous community of Castile and León, Spain. The Condado de Treviño and the geographically smaller La Puebla de Arganzón make up the enclave of Treviño. Although the enclave is part of Burgos (and, hence, part of the autonomous community of Castile and León) it is surrounded by the province of Álava, part of the autonomous community of the Basque Country. Hence, properly speaking, the enclave of Treviño is an enclave within Álava, and an exclave of Burgos.HistoryAn abundance of prehistoric remains testify that the Condado de Treviño has been inhabited since ancient times. In pre-Roman times, the Varduls, Caristios and Autrigones all lived here at one time or another, attesting to the region's strategic importance.At the beginning of the 11th century, Alavese comarcas of the river Ivita began to be established, in the basin of what is now known as the River Ayuda, a tributary of the Zadorra, between the Montes de Vitoria to the north and the Sierra de Toloño and other ranges of the Sierra de Cantabria to the south. The name Treviño may stem from "Trifinium", postulated as Latin for 'boundary of the three tribes'.
