Eric of Pomerania, king of Denmark, Norway and Sweden (at that time a unified kingdom), built a castle on the site now occupied by Malmöhus in 1434. The strategic location was of great importance. From here, the west side of the city could be protected and shipping traffic on the southern part of the Öresund monitored. Malmöhus acquired its present appearance following major reconstruction in the mid 16th century when King Christian III ordered the building of a modern fortress, splendid Renaissance castle and county governor´s residence, all on the one site. Denmark´s coins were minted here in the Middle Ages. Crown Prince Frederick held wild parties here in the 16th century. Prisoners were beheaded in the courtyard in the 19th century. Malmöhus has now been restored in the spirit of the 16th century and is part of the Malmö Museums, the largest museum in southern Sweden. The castle is part of Sweden´s cultural heritage and is managed by the National Property Board. https://malmo.se/Uppleva-och-gora/Besoksmal/Malmo-Museer/Sprak/In-English/Malmohus-Castle.html

Stjärnorp manor ruins are ruins of a 17th-century manor of the northern shore of Lake Roxen. The manor burned down in 1789 and the main building was never restored. Stjärnorp's castle was erected in 1655–1662 (in the parish of Vreta monastery ) by the Count and Field Marshal Robert Douglas (1611–1662). The castle and terraces were designed by Nicodemus Tessin. According to a story, it is said that when the war comrades and arms brothers Robert Douglas and Axel Lillie came home from the Westphalian peace, they entered into an agreement to build their respective castles, Stjärnorp's castle and Löfstad castle, so high that they could see and send greetings from the top floor to each other. All buildings were destroyed by a fire on May 12, 1789, but the castle chapel was restored already that year. The wing buildings were also rebuilt soon but financial resources were lacking for the main building, which is still a ruin. https://visitlinkoping.se/en/do/attractions/castles-and-manors/stj%C3%A4rnorps-slottsruin
