Beer, wool and tobacco made Amersfoort an exceedingly rich town from the 16th century onwards. Well-heeled with a touch of the provincial, the town has many striking merchants' homes that have been lovingly restored. And the egg-shaped old town offers quiet, wonderfully evocative strolls along canals and narrow alleys that still ooze medieval atmosphere.
Amersfoort makes for a good break on a train journey to/from Friesland or Groningen. You can have an interesting stroll of an hour and then get a good meal.
