Sisterdale Valley District
Why it's listed
Sisterdale is a small Hill Country community in Kendall County, Texas, founded in 1847 in the valley of the two Sister Creeks. This historic district centers on Badenthal, a private farm whose buildings reflect the town's early German settlers. Nicholas Zink built a windowless log block house there around 1847. Ernst Kapp, a German professor and political refugee, bought it in 1850, expanded it with a dog run and second story, and added stone buildings used as a hydropathic institute in the 1850s. A log coachhouse, smithy, cypress barn, smokehouse and sugar press also survive. A second complex built by the Langbein family from the 1870s to 1910 shows the later generation of German farmers. An 1893 stone schoolhouse stands at the entrance. The district is significant as the only surviving physical record of Sisterdale's Latin Colony of educated German intellectuals and the transition to later immigrant farming families.
Significance in brief: The nomination argues that Badenthal holds the only surviving buildings from Sisterdale's Latin Colony, a settlement of well-educated German political refugees founded in the late 1840s. It also preserves later Langbein family buildings that show the shift to a more permanent generation of German farmers. The district is also linked to Ernst Kapp's water-cure institute and to the early school system.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
