Inside the Harbour Light Tower.

Enjoyed some quality time with my younger son today.
The tower was built in 1817 by Stevenson, builder of many lighthouses off the coast of Scotland. It played a vital part in ensuring safe passage across the Forth Estuary at the Queensferry passage, for a long time a major part of Scotland’s transport network. The tower is 7m high and contains a light system that burned oil for the lamp; this light was a fixed beam and a parabolic reflector sent the beam forward; it was a great navigation beacon for the ferries. The lamp oil was originally whale oil.
The tower sits at the land end of the Town Pier in North Queensferry. The pier was in use until the Forth Road Bridge, upstream, opened in 1964. The Forth Bridge, downstream, was completed in 1890.
