In 1652, the keel was laid down at the Admiralty shipyard in Rotterdam for a new Dutch Admiralty flagship. The project was led by shipbuilder Jan Salomonszoon van de Tempel, who had also designed the previous flagships Aemilia (1633-1647) and Brederode(1644-1658). A year later however, the project was overtaken by the United Provinces and moved to Goossen Schacks wharf in Dordrecht. When the Eendragt as the ship was named, was completed in 1654 , it was largely armed with guns from the Aemilia.
Ten years later, having participated in several major actions, such as the Battle of the Sound (1658), the Eendragt had in turn become obsolete and was to be replaced by the 7 Provinciën. Another relocation of the cannons would however, never take place.
Cluster of cannon
When the Netherlands Institute of Ship and underwater Archeology (NISA), a predecessor to the Cultural Heritage Agency of the Netherlands once mapped all cannon that had been salvaged in the North Sea in the 60s, 70s and 80s, a pattern began to emerge. It turned out that the largest cluster of finds, near the Nieuwe Ankerplaats, consisted exclusively of bronze cannon made by Cornelis Ouderoggein from Rotterdam and Coenraet Wegewaert from the Hague. Also considering the large caliber of the guns, NISA concluded that the cluster indicated a wreck site of a large and important warship, perhaps even a flagship. The only one such ship to have sunk in this region, and in the period suggested by the cannon turned out to be the Eendragt.

In 1987, the Dutch Ministry of Infrastructure and the Environment was conducting a survey of the North Sea seabed using a remotely operated vehicle. At the Nieuwe Ankerplaats, at a depth of around 38 meters, they stumbled upon an area full of bronze cannon, fragments of wooden ship construction and rope waving in the current. Similar finds yet in smaller numbers were found in the vicinity of the site, in correspondence with the explosive fate of the Eendracht. Becauseof the great depth however, the area has never been subject to archaeological investigation.
