Cultural Heritage in the Baltic Sea States         Dark Times Ahead           Until recently it was the keeper’s duty to keep watch and ensure that the lighthouse remained alight from dusk until dawn. In addition he played an active role in the daily maintenance of the lamp, its equipment, and the buildings. The introduction of fully automated lights has lead to a rapid decline in the number of manned lighthouses. In the 21st century the majority have been fully automated. Lights are also threatened by satellite based navigation, which could eventually replace lighthouses and lights as primary navigation aids. The lack of regular maintenance at decommissioned and demanned lighthouse stations leads to many of them becoming seriously neglected.     The Keri lighthouse was first established in 1719. In 1803 it was the first lighthouse along the Estonian shore to use lamps and reflectors. It has sustained severe damage over the years and plans are now underway to restore the lighthouse. © Danckert Monrad-Krohn. Grip, Norway established 1888.
