A Nacogdoches structure has been named to the Preservation Texas' 11th annual list of Texas' Most Endangered Places. The Clay House at 720 Bois d'Arc was built circa 1905, according to Preservation Texas. A press release says the Clay House is considered to be the finest house in the Zion Hill Historic District of Nacogdoches. The house was built for Charlie Clay and his family, and is an important example of vernacular architecture in one of the most intact early 20th century African-American working class neighborhoods in Texas. The release says the Clay House celebrates the contributions of African-Americans to the history of the Zion Hill neighborhood. Significant repairs would be needed in order for the structure to be a museum. Another deep east Texas site, the Mary Allen Seminary in Crockett was also named to the Most Endangered Places list.
