moats surrounding Nyborg Castle stretch out along the center of the city. The moats appear as they did in the Middle Ages, with the same water regulation systems still in use. Three of the original bulwarks still exist, with the remaining having been torn down during city expansions. Two of those bulwarks are located around Nyborg Castle, and are known as the Queen's Bulwark (Danish: Dronningens Bastion) and the Crown Prince's Bulwark (Danish: Kronprinsens Bastion). Those are surrounded by the original ramparts, which today act as park areas. On the Queen's Bulwark is a water tower from 1899, built by Emil Swanenflügel. The water tower was protected in 1997. The third bulwark is called Prince Carl's Bulwark (Danish: Prins Carls Bastion), and is slightly smaller. It also acts as a park area. Holckenhavn Castle Bordering the city of Nyborg to the south is the Holckenhavn Castle. The castle owns 900 acres, and perform forestry, farming, hunting and renting out of residential houses. The castle itself can be rented for weddings and similar events, and also have hotel-services. The manor originates from around the late 1300s, where it was owned by Anders Jacobsen Ulfeldt. The manor was kept in the Ulfeldt family, and in 1534-1536 during the Count's Feud, the manor was owned by Knud Ebbesen Ulfeldt, who defended the castle of Gjorslev on Sjælland against the peasants. He supported Christian III after the war. Knud Ebbesen Ulfeldt died in 1540, and the manor was given to his son, Corfitz Ulfeldt. He, however, was secretary at the Danish chancery, and the day-to-day management of the manor was instead performed by his mother, Anne Eriksdatter Hardenberg. Jacob Ulfeldt gained the manor after Anne Eriksdatter Hardenberg's death in 1564. Jacob Ulfeldt fought under both Herluf Trolle and Daniel Rantzau in the Seven Years' War. After performing well in the war, he was sent to Russia as a delegation, but failed to improve Denmark's relationship with Russia. This upset the king, and Jacob Ulfedt spent the rest of his days taking care of Holcekhavn Castle. He made large improvements, and expanded the manor significantly during this time. In 1616, the manor was sold to Ellen Marsvin, who made big changes to the interior of the castle. During the Dano-Swedish War, the manor was owned by Leonora Christine and Corfitz Ulfeldt. Holckenhavn Castle was largely ignored by the Swedes, due to Corfitz Ulfedt's relationship with
