1728: A "Praecis Chart over Lindesnes in Norway"

In addition to his operations of the lighthouse, Bornholm financed work on an unusually detailed chart of the waters around Lindesnes.Accurate published in different versions ranging from nautical charts to more decorative varieties, it must have been based on painstaking measurements by skilled experts.

But Bornholm himself was not at Lindesnes very often. He was an investor, manager and administrator with a town house in Drammen, farm at Slagen and his own saltworks in addition to the lighthouse.

He owned horses and carriages, of course, as well as a so-called journey- boat to use when supervising his various enterprises. But he never lived permanently at the lighthouse.
