|PORTLAND BILL LIGHTHOUSE|
A red sector light warns mariners of the hazardous Shambles Bank which lies about 3 miles off shore.
The lighthouse was established in 1716 and the height of the tower is 41 metres. In 1996 the whole lighthouse became automated with the light flashing 4 times every 20 seconds. The range of the light is 25 nautical miles.
During fog the horn is activated and this gives a 3.5 second blast every 30 seconds.
For some of my childhood years I lived at Portland and the lighthouse was a constant backdrop to a lot of my early adventures.
