The resulting gap on the eastern side of the Rhine contained the Wisper valley, the towns of Lorch and Kaub, and villages of Lorchhausen, Sauerthal, Ransel, Wollmerschied, Welterod, Zorn, Strüth and Egenrod.
Apart from the south, this region is hardly dissected by any public roads and is only populated in the south – in the villages of Schnellbach and Struth-Helmershof in the municipality of Floh-Seligenthal, the Rotterode, Unterschönau and Oberschönau suburbs of Steinbach-Hallenberg and the town of Zella-Mehlis.
