Over time, people have thrown things into the river or lost them. Now, almost 700,000 finds were collected from all periods. Analysis is focused on dating and spatial distribution in order to find patterns of use. And indeed patterns occur, pointing to a rich 17th century sugar industry (pottery), city defence (weaponry) and boating (ship hooks 1300-1900 AD). Also, finds from the Far East were collected, evidence for the East Indies Company (VOC), many personal belongings (Dutch gin bottles), pilgrim insignias and evidence for wool production. Analysis is still in progress.
