The Spanish Empire left a huge cultural, urban and architectural legacy in the Western Hemisphere. Hundreds of towns and cities in the Americas were founded during the Spanish rule. The tangible heritage includes universities, forts, cities, cathedrals, schools, hospitals, missions, government buildings and colonial residences, many of which still stand today. A number of present-day roads, canals, ports or bridges sit where Spanish engineers built them centuries ago. The oldest universities in the Americas were founded by Spanish scholars and Catholic missionaries. The Spanish Empire also left a vast cultural and linguistic legacy. With over 470 million native speakers today, Spanish is the second most spoken native language in the world, as result of the introduction of the language of Castile—Castilian, ""Castellano"" —from Iberia to Spanish America, later expanded by the governments of successor independent republics. Another cultural legacy of the Spanish empire overseas is the Catholic Church, which remains the main religion in the Spanish Americas. The cultural legacy is also present in the music, architecture, cuisine and fashion of much of Spanish America.
