Pampus is a man-made island and sea fort located in the IJmeer near Amsterdam. The fort was commissioned in 1895 to protect the IJ bay and harbour of Amsterdam. There is a well-known Dutch expression "lying for Pampus" (voor Pampus liggen) describing people that are lying down knocked out. It stems from the time ships had to wait for high tide at the Pampus sandbank/shallows before they could enter the harbour of Amsterdam. | Stuff Dutch People Like
