History

The Woerden 7 was a Roman flatboat. These kind of ships are well known in the Netherlands. Similar ships were found in Zwammerdam during the 70s and De Meern in 1996.

It is a simple type of ship, a flat horizontal bottom with vertically brims. The mast was located at a third from the ship's front.
These ships were used to transport goods or people.

Rowing facility

Unique evidence concerning the way of propulsion on the Woerden 7. Notches in a horizontal board may be used to secure seats on which the crew sat while rowing. On a vertically board holes were found. These holes showed wear-damage which is probably caused by oars.

Shoes

At the bottom of the rowing-facility, leather shoes were found. It was assumed that rowers took out there shoes while rowing, to gain better grip on the wet and slippery wooden floor.

Discovery in June 2003

During the construction of a profile at the Nieuwe Markt in Woerden, the remains of a shipwreck were found by an archaeological company. The wrecks date was estimated at 158 AD.

A three-day pilot-study was planned to learn more about the wrecks exact location, length, the conservation state and its surroundings. This pilot study was realized in August 2003.

The excavation took place from September until November 2003, the development and reporting from June 2005 until January 2007.
