Creil Woods around the year 1100. The exact position of the forest is unknown

The All Saints' Flood of 1170 (Allerheiligenvloed) was a catastrophic flood in the Netherlands that took place in 1170. Large parts of the Northern Netherlands, and Holland territories were overflowed.

The flooding North Sea created the islands of Wieringen and Texel.[1] Lake Flevo was once a fresh water lake, but a sea channel opened a connection from the North Sea into the lake through Creil Woods, and turned the lake into the salt-water sea known as the Zuiderzee. The Creiler Woods vanished under the waves. The sea area increased inside the Netherlands and large peat areas developed, which were easily washed away.
