Kobbergrund
# Kobbergrund

Kobbergrund is a shoal in the Kattegat 11 kilometers (7 miles) East South East of the Danish island of Læsø, lying close to the main shipping lanes from the south.

## Shipwrecks

It is the site of several shipwrecks, including the Russian ship Baron Stieglitz in 1840 and the earlier Printz Friderich, a Danish ship-of-the-line in 1780. The wreck of the latter was newly discovered in 2018 by a team using modern survey equipment. The shoal was known in English as "Kobber Ground".

## Survey

The survey of Danish coasts and waters begun in 1791, and restarted after a hiatus in 1827, saw the first general chart for the Kattegat published in 1844. On 20 November 1853 the Danish government anchored a lightvessel on the Ground at 57°8′30″N 11°20′30″E﻿ / ﻿57.14167°N 11.34167°E﻿ / 57.14167; 11.34167. The vessel was schooner-rigged, painted with a white cross on each site, and carried three lights on her mast.

## Lightships

The Danish government stationed lightships at Kobbergrund from 1853 to 1908.
