AUSTIN - Eight sites ranging from a landmark East Texas church to a West Texas poor farm to two sites linked to the heyday of railroads in the Lone Star State were named Thursday as Texas' Most Endangered Places, a list of historically significant resources that are in danger of being lost forever. At a press conference outside the Texas Capitol, the history advocacy group Preservation Texas announced its 12th annual list in hopes that public attention drawn to the sites may spur efforts to save them. "The 2015 list is a diverse group of sites that reflect the range of preservation issues that historic places throughout the state are confronting," said Evan Thompson, executive director of Preservation Texas. [...] several demonstrate the potential impact of the new state historic preservation tax credit as an incentive for saving endangered sites. Historic sites named to the list of Texas' Most Endangered Places represent some of the best opportunities to make a positive economic impact on local communities through preservation, particularly through the use of the new state historic preservation tax credit, he said.
