Søborg Castle

[3] [4] Traditionally, Archbishop Eskil of Lund is said to have expanded the previous buildings to a real castle with defensive walls and a moat.

Saxo Grammaticus wrote that Eskil had built a castle in the den lethriske mose, but it is unknown whether that is a reference to Søborg.

No-one has so far been able to make a clear connection between Eskil and Søborg either by archaeological finds or written sources.

[6] In 1985, Danish historian Robert Egevang (1939–2008) led an excavation of two trenches to determine the conditions between the octagon tower and the castle proper.

The excavations show that the castle proper was erected in the late 13th century, which would make it impossible that Eskil was the builder, as he died in 1181.
