The bronze canon of the Alphen
In 2007, while renewing the quay of the Kleine Werf, a bronze canon was found eight meters below the surface. Further investigation showed that the gun came from the frigate Alphen that exploded and sank in 1778 in the port of Willemstad. Because of the explosion the canon was slung into the water and landed at the Kleine Werf. Because no one had seen that, that place was not searched. Later the Kleine Werf was expanded and a quay was built over the canon.
