W. Elst at the European Southern Observatory. Berg op Zoom, a city dating from 1287 in the southern part of The Netherlands, was a fortress held by the Geuzen during the Eighty Years War. Unsuccessfully besieged by Farnese in 1587 and by Spinola in 1622, this famous rebellion is archived in the beautiful hymn Merck toch hoe sterck.
