As time passed, a problem
developed in differentiating the light beacons from one another. Two more
lighthouses were built at Lista in 1853 to avoid the confusion. This
arrangement lasted until 1872. By that time, new blinking apparatures had
been invented, allowing the lights of each tower to be recognizably
different. Therefore, two of the lighthouses was dismantled and removed.
The lighthouse station at Lista has also had a foghorn and a visual signal
station (semaphore) where the lighthouse-keeper could send messages to
passing ships by raising different flag combinations on the nearby
embankment. In addition, the fog signals were syncronized with the
radiosignals from the lighthouse so that the ship captains could calculate
the distance to land by timing the difference between the radio signals and
the sound signals.
The Fog Horn
In 1880 the lighthouse got the
strongest foghorn of that time.
The lighthouse also had a visual signal-station (semaphore), where the
lighthouse-keeper could send messages to passing ships by raising different
flag-combinations on the flagpole located on the nearby embankment.
In addition, the radiosignals were synchronized with the beacon lights of
the lighthouse, so that the ship-captains could calculate the distance to
land by timing the difference between the radiosignals and the
sound-signals.
In 1932, the same year as the lighthouse got electricity, a modern
signal-horn was installed.
In 1988 the foghorn was closed down. |
