A north-east lighthouse was re-lit last night to mark the anniversary of automation.
And Kinnaird Head, in Fraserburgh, will shine until 8pm tonight to commemorate the occasion.
The event has been organised by the town’s Museum of Scottish Lighthouses and has brought together former keepers from across Scotland.
It was lit at 8pm last night by Ron Morrice, a former keeper and current chairman of the museum committee.
He said: “It’s the biggest and most ambitious events the museum has hosted.
“We’ve managed to get quite a number of former keepers here which is, in itself, is an achievement.
“It’s gone well so far. It’s freezing, but this is a lighthouse keeper’s duty.”
Michael Strachan, the museum’s collections manager, has spearheaded the effort to bring the keepers to Fraserburgh.
He said: “When you work in the lighthouse museum you are aware of certain key dates, and we knew this anniversary was coming up.
“We thought it would be especially good to mark because as time goes on there’s less and less keepers.”
Guest keepers through the night included North Ronaldsay keeper Billy Muir and former Fair Isle South caretaker Bill Gault.
Tours also took place around the museum and Kinnaird Head until 6am.
They resume this morning until the closing ceremony of the celebration tonight at 8pm.
The last manned lighthouse, Fair Isle South, was de-staffed on March, 31, 1998 when all four keepers departed the premises.
The symbolic event was marked with a simple ceremony attended by Princess Anne, the patron of the Northern Lighthouse Board.
Kinnaird Head was last re-lit for it’s 225th anniversary in December 2012.
Since then it has become a focal point for various events and celebrations in the town.
In 2015, the whole building was bathed in pink light for a local charity – the Moonlight Prowl.
