The prince-bishop was also lord of Bischofszell (lower part of map) although effective power over that town had passed to the Swiss Confederacy and the canton of Zurich.<br>
Cropped out of a map centered on the Swabian Circle titled Circvli Sveviae Mappa designed by Johann Matthias Hase and published by Homann Heirs (Homann Erben) in 1742.
