This is a Texas historical marker telling the story of Clara, a former German settlement near Burkburnett, rather than a preserved ghost town with buildings to explore. The marker is a roadside stop, although the Texas Historical Commission currently indicates that the physical marker is being replaced, so travelers may temporarily find no plaque on site.
