A broken balance arm draws the engineer, supervisor’s wife, Nicolaus Cruquius and Johanna into one mystery, ending with the great engine in motion.

What you need to know

Cruquius Museum runs 45-minute Living History tours at 13:00 and 14:30 on 19 July. Adults add €2.50 to museum admission and under-18s pay no surcharge; choose a slot to understand Dutch water history as a family mystery.

  • Set in 1851, four characters investigate the broken balance arm and ask whether King Willem I or Nicolaus Cruquius truly commands the future of the reclaimed land.
  • Cruquius, born Kruik, was a surveyor, cartographer, astronomer and early systematic weather observer; his name now belongs to the pumping station that helped drain Haarlemmermeer.
  • The great engine is demonstrated, so this is more than acted dialogue; adult museum entry is €17.50 before the surcharge, while Museumkaart and other passes may cover admission.

Hokimi field note: Ask children to guess who broke the arm before entering and compare the answer afterwards; one live question makes both machinery and characters easier to remember.
