The Netherlands issued two stamps in 1982 with designs of fortress plans. The low value has a section of the ground plan of the fortress at Enkhuizen on the Zuider Zee, built between 1590 and 1600 by the military engineer Adriaen Anthoenisz van Alkmaar. The design is based on a manuscript dating from the end of the 18th century.

     The design on the high value is part of the ground plan of the fortress at Coevorden, after it was rebuilt about 1680-1685 by Menno Baron van Coehoorn. The design is based on a sketch drawn about the year 1750, now in a private collection.
