The villages Strijen, Strijen-Sas and Cillaershoek are also part of this municipality. As early as 630 AD Strijen is named in history sources because of a bloody battle in this area between the Frisians and the Franks. Strijen must have been a part of the land of Taxandria, which extended over the present area, a part of Noord-Brabant and a piece of Belgium. The area was cut through by the small river the “Striene”, possibly the origin of the name.
In Strijen-Sas the nature reserve “De Esscheplaat” can be found along the Hollandsch Diep. It comprises a tidal wood with creeks and reed marshes. Really splendid walks can be made here. The museum Het Land van Strijen tells the history of the inhabitants of the eastern part of the Hoeksche Waard and archaeological finds can also be seen.
