The Cantelmolinie is part of the State-Spanish Lines and connected Fort St. Donaas with Fort Isabella. The line featured seven redans (strongholds with two sloping sides) and several redoubts (small field entrenchments with projecting corners). The line was named after Andreas de Cantelmo; he rebuilt the Line of the Dirty Canal into its current form. That canal can still be seen in the landscape today. Because of this you can still recognize the line very well.
