This unique home in Seguin, Texas features inventive architecture and a somewhat complicated history. Built from limecrete—a mixture of lime, water, and gravel—the Sebastopol House helped coin the nickname “City of Concrete” for Seguin, but it was built by enslaved people. Today, the house honors the region’s Black heritage by featuring the Wilson Pottery Foundation, which was founded by Hiram Wilson and his brothers, and is considered to be one of the first Black-owned businesses in the state of Texas.
