Weesp
A town that Holland deliberately over-fortified — then flooded on purpose to hold back armies.

City rights since 1355, Weesp spent centuries as an outsized military post on the river Vecht, Holland's defensive front line from the late Middle Ages to WWII. Its inundation fields were part of the Stelling van Amsterdam — the circular flood-defense ring around the capital, now a UNESCO World Heritage Site. The town rarely held more than a few thousand people; the fortifications were built anyway.
What to look for
- The Sint Laurentiuskerk tower, which carries a Pieter Hemony carillon cast in 1671 and still used for Protestant services
- The river Vecht, the physical line Holland's military planners held from the Middle Ages through WWII
- The low-lying polder landscape — the inundation zones designed to flood on command as part of the Hollandic Water Line
Weesp merged into Amsterdam municipality on 24 March 2022, sitting on the Vecht and the Amsterdam-Rhine Canal at Amsterdam's eastern edge.
