Organisers have hailed the fourth annual LewesLight festival as “the most successful yet”.

The event, which was staged from October 12-14, saw thousands of guests visit a series of sixteen installations centred around the town’s historic castle.

The theme of this year’s event was “Missing”, which drew inspiration on the events of 100 years ago, including the end of the First World War in which millions died and scores more were declared missing.

A spokeswoman for the event organisers, Lianne Jarrett, said: “Installations in the castle precincts and beyond were really inspired.

“It was a truly immersive experience involving light, sound and creative design, and I think everyone who visited was moved in some way.”

Among the installations was a display to celebrate the memory of pioneering electrical engineer Dame Caroline Haslett, who was born in 1895 in Sussex.

Dame Haslett made groundbreaking discoveries in the 20s and 30s which helped harness the power of electricity to emancipate women from the drudgery of household work.

Her work was commemorated in the popular “Watt’s in a Home”, which display offered visitors the chance to use pedal power to light up an electric bulb.

Other busy exhibits included the illuminated sheep and the castle walls.
