Article: In addition to the cathedral, Strasbourg houses several other medieval churches that have survived the many wars and destructions that have plagued the city: the Romanesque Église Saint-Étienne, partly destroyed in 1944 by Allied bombing raids, the part Romanesque, part Gothic, very large Église Saint-Thomas with its Silbermann organ on which Wolfgang Amadeus Mozart and Albert Schweitzer played, the Gothic Église protestante Saint-Pierre-le-Jeune with its crypt dating back to the seventh century and its cloister partly from the eleventh century, the Gothic Église Saint-Guillaume with its fine early-Renaissance stained glass and furniture, the Gothic Église Saint-Jean, the part Gothic, part Art Nouveau Église Sainte-Madeleine, etc. The Neo-Gothic church Saint-Pierre-le-Vieux Catholique (there is also an adjacent church Saint-Pierre-le-Vieux Protestant) serves as a shrine for several 15th-century wood worked and painted altars coming from other, now destroyed churches and installed there for public display. Among the numerous secular medieval buildings, the monumental Ancienne Douane (old custom-house) stands out.

Article: and Camargo. In 1631 Juan Rangel de Biezma discovered a rich vein of silver, and subsequently established San Jose del Parral near the site. Parral remained an important economic and cultural center for the next 300 years. On December 8, 1659 Fray García de San Francisco founded the mission of Nuestra Señora de Guadalupe de Mansos del Paso del Río del Norte and founded the town El Paso Del Norte (present day Ciudad Juárez) in 1667. The Spanish society that developed in the region replaced the sparse population of indigenous peoples. The absence of servants and workers forged the spirit of northern people as self-dependent, creative people that defended their European heritage. In 1680 settlers from Santa Fe, New Mexico sought refuge in El Paso Del Norte for twelve years after fleeing the attacks from Pueblo tribes, but returned to Santa Fe in 1692 after Diego de Vargas recaptured the city and vicinity. In 1709, Antonio de Deza y Ulloa founded the state capital Chihuahua City; shortly after, the city became the headquarters for the regional mining offices of the Spanish crown known as Real de Minas de San Francisco de Cuéllar in honor of the Viceroy of New Spain, Francisco Fernández de la Cueva Enríquez, Duke of Alburquerque and the Marquee of Cuéllar..

Question: How many years was Parral an important economic and cultural center?
