For more than a hundred
years the Harlinger family Ratsma were the town's carilloneurs - they
determined the daily rhythm in the town. They were also clockmakers and they had so much craftsmanship, knowledge and insight that they were able to make complex clockworks. Some clocks not only
indicated the time but also the day, the month and the year as well as the
position of the sun, the moon and the planets.
In the museum the oldest 'horlogerie' is also the most special. At the top of the clockface there is a
'planisferium': a kind of disc on which the celestial map is portrayed. You
will have to stretch to see the stars however, even indoors they are high in
the heavens with such a tall clock! The clock also contains a chiming mechanism
which plays twelve melodies including a free interpretation of the Dutch
National Anthem, known as the Wilhelmus.
