Landskrona Citadel has use fortification
History
Initially built by Christian III of Denmark 1549–1559 as a purely defensive fortification with two complete moats, the inner with a width of 70 metres (230 ft). The outer (complete) moat is between 40 and 70 metres (130 and 230 ft) wide, and has cross fire bastions for artillery and guns. Outside the outer moat, a third narrower moat covers the northwest and northeast. There also exist remains of a fourth moat (between the two outer moats).  
The fortifications and moats system surrounding the castle is known to be one of Europe's largest and best preserved. 
In the area between the outer and far outer moat resides the oldest area of allotment-garden cottages of Sweden.
