DE BURCHT VAN GRAAF EDZARD IN DE STAD GRONINGEN, 1506-1514

Samenvatting

The 16th century brought revolutionary changes in the way of waging war in Eu­rope. Research into the building of forti­fications in the days of Count Edzard I of Oostfriesland may contribute to a better in­sight in the way in which innovations were introduced in the areas of Friesland and Groningen. By means of a combined histo­rical-archaeological investigation many data on the stronghold of Count Edzard in the city of Groningen (1506-1514) could be recovered. Especiaily noteworthy is the way in which the expense was limited by using the pre-existing city defenses. The late­medieval stronghold seems to typify the transition to the Modern Age. For defense the emphasis now clearly was on the earth­en walls, which were provided with a good flanking. Certain innovations may possibly have been adopted from Duke Albrecht of Saxony.
