Lopikerwaard

Originally an area of swampland, the polder was developed from the eleventh century CE. Many canals were dug in order to drain the land, dividing the land into equally sized plots which still define the landscape.

The polder area is bounded by the Hollandse IJssel river to the north and north east, the Lek river to the south and the Krimpenerwaard polder to the west. Several larger drainage canals cross the polder from east to west. The area largely coincides with the municipality of Lopik, whence it gets its name. The landscape is defined by large areas of pasture lands and linear settlements.
