Kostverloren is the hornwork designed to protect the Delfzijl fortress from attacks from Farmsum. Between Kostverloren and the center of Delfzijl lay the locks, where Delfzijl thanks his name. Military role and declaration of names
During the French time in the Netherlands Kostverloren had an important role in the defense of Delfzijl. Because the French Delfzijl reinforces additional wildlife, the hornwork has been expanded. During the Siege of Delfzijl (1813-1814), which ended the French era, the reinforcement came in handy; The invaders exercised great pressure on this flank.
The name "Kostverloren" can be explained by its military function: if this part of the fortress was conquered, the cost was lost. Cost loss after the vesting period
After the fortress lost its function, Kostverloren had a shipyard. The shipyard was known as the 'Buitenwerf'. In the same period, around 1850, the first houses came on Kostverloren. Initially, these houses belonged to Delfzijl, later the area belonged to Farmsum. When the Delfzijl port was dumped, the hornwork was largely excavated. The district of Kroonstad is partly on the ungraved part of the hornwork. Also see
