Any further plans for Landskrona were however not realized, for various reasons. The continued Swedish-Danish wars favouredKarlskrona, located at a safer distance from Denmark, replacing Landskrona as a naval base, the fortifications were discontinued, and Malm� remained the most important commercial town - despite Malm� lacking a harbour until the late 18th century. The fortifications at Landskrona were expanded considerably between 1747 and 1788, but were condemned in 1822, where after the garrison was abolished in 1869. The walls and moats of the fortifications are today a beautiful recreational area, commonly known as the Landskrona Citadel. On its northern side an allotment-garden area of cottages was founded in the final years of the 19:th century. It's the oldest of its kind in Sweden today.
After the industrial revolution and the urbanization the town grew fast. During the first World War a large shipyard, �resundsvarvet was started. But after the war the fast growing of Landskrona slowed down while nearby towns like Helsingborg, Lund and Malm� continued to grow. In the mid 1970's the shipyard had more than 3500 people employed - and the town had only 30.000 inhabitants (38.000 in the municipality). When the shipyard closed in 1983 a 20 year long depression began. But slowly the town has recovered. In 2001 a new railway station was inaugurated. This was very important for the town, since the old station was a terminal for southbound trains only. The new station is along the dual fast railway between Copenhagen and G�teborg, and all trains stop at the station.
For many years Landskrona had car ferries to Copenhagen. After the last ferry line closed in 1993 passenger traffic with high speed ships continued to traffic Copenhagen but after the �resund bridge opened in summer of 2000 also the passenger traffic to Copenhagen ended
