In the periods 1812 - 1817 and 1832 - 1984, the hamlet of Cillaarshoek and the hamlet and polder of Sint Anthoniepolder were also part of the municipality of Maasdam.The municipality of Maasdam was eventually merged with some surrounding municipalities to become part of the new municipality of Binnenmaas.
