Bad Mergentheim, Germany

At just 24,752 residents, Bad Mergentheim hardly qualifies as a bustling metropolis. While its status as an official spa town brings some tourist appeal, the sleepy pace of life and heavy bureaucracy are likely to test the patience of many outsiders. The town's history as the headquarters of the Teutonic Order lends a quaint, medieval charm, but the lack of modern amenities and cultural vibrancy may leave some newcomers feeling isolated. For those seeking a quiet, old-world German town to while away their retirement, Bad Mergentheim could be a good fit - but adventurous types should look elsewhere.
