Holckenhavn Castle is a manor house located next to Holckenhavn Fjord, an arm of the Great Belt, just south of Nyborg on the east coast of Funen, Denmark. The current Renaissance castle was built in the late 16th and early 17th century by three consecutive owners. Previously known both as Ulfeldtsholm and Ellensborg, it received its current name in 1672 when it was acquired by Eiler Holck, who at the same time founded the Barony of Holckenhavn.
Hesselagergård, Fyn - Den nævnes i 1200-tallet som krongods i Kong Valdemars Jordebog. Johan Friis lod i årene 1538-1550 opføre den nuværende Hesselagergård, og gården blev i slægtens eje til 1682, hvor den blev frasolgt.
