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.
