The United Nations Educational, Scientific and Cultural Organization or UNESCO has announced new additions to the 'World Heritage' list. Among the latest entrants is the Alamo and several other historic Spanish colonial Catholic sites, known together as the San Antonio Missions.
According to UNESCO, "The complexes were built by Franciscan missionaries in the 18th century and illustrate the Spanish Crown's efforts to colonize, evangelize and defend the northern frontier of New Spain."
Highlighting their significance, UNESCO notes, "The San Antonio Missions are also an example of the interweaving of Spanish and Coahuiltecan cultures, illustrated by a variety of features, including the decorative elements of churches, which combine Catholic symbols with indigenous designs inspired by nature."

In this photo taken June 3, 2014, the Elwha River flows freely through what was Lake Mills and past the old Glines Canyon Dam, bottom, in the Olympic National Park near Port Angeles, Wash. The final chunks of concrete are expected to fall this September in the nationâs largest dam removal project, but nature is already reclaiming the Elwha River on Washingtonâs Olympic Peninsula. So much sediment, once trapped in reservoirs behind two hydroelectric dams, has flowed downstream that it has dramatically reshaped the riverâs mouth, replenished eroding beaches and created new habitat for marine creatures not observed there in years. Meanwhile, Chinook salmon and steelhead have been streaming into stretches of the Elwha River and its tributaries previously blocked by the Elwha Dam, which stood for nearly a century before it came down in 2012.
