Zieriksee, a town in the province of Zeeland, Holland, on the south side of the island of Schouwen. Pop. 6800. It is a very old town, and formerly flourished exceedingly on account of its trade and fishing, and important salt-making industry, and now is the chief market centre and port in the island. Among the principal buildings are the town-hall (15th century); the Great Church, which was rebuilt after a fire in 1832, but retains the lofty tower (1454) belonging to the earlier building; the Little Church, the prison and the exchange. The chief public square occupies the site of a residence of the counts of Zeeland dating from 1048.
