At the other side of the river in the Commewijne district, where the Commewijne River and the Suriname River come together, there is another fort. It is fort Nieuw Amsterdam. The fort was built in the 18th century to protect the plantations. When the plantations were no longer profitable most of them closed. And the fort lost its defending position. The district government used the buildings from 1907. Later a part was used as prison. The prison closed in 1982.
Today the fort is an open air museum. You can see some old buildings, and have a look in the cell block.
