When were holland's dykes built?

Answer 1

The construction of dykes in the Netherlands, commonly referred to as "Holland's dykes," began in the Middle Ages and continued into the early modern period. Significant developments occurred from the 11th century onwards, with major projects in the 12th and 13th centuries during the reclamation of land from the sea. The most famous dykes, such as those in the Zuiderzee area, were completed in the 20th century, particularly with the construction of the Afsluitdijk in the 1930s.
