2 Best Sights in Kreuzlingen and Konstanz, Eastern Switzerland

Arbon

Between Romanshorn and Rorschach on Highway 13, Arbon sits on a little promontory jutting out into the Bodensee, surrounded by lovely meadows and orchards. It was a Celtic town before the Romans came in 60 BC and built military fortifications. Evidence of the Romans (who called the place Arbor Felix) can be found in an interesting collection of relics in the late-Gothic St. Martinskirche.

Romanshorn

About halfway between Kreuzlingen and Rorschach (follow Highway 13 east along the Bodensee) you'll come to the small town of Romanshorn. An industrial town and an important ferry port for Friedrichshafen in Germany, this is also a surprisingly enjoyable resort with fine views of the Swiss and Austrian mountains.
