Chatsworth was illuminated by a stunning river display as hundreds of pulsating lights floated down the Derwent as part of a stunning art project.
The Derwent Pulse project reached the Chatsworth grounds on Saturday night, with 50 youngsters from the nearby Pilsley School helping to shepherd the lights along while wearing special outfits made for the event.
The spectacular display took place after darkness had fallen, with Chatsworth House also floodlit to give it a magenta appearance.
The project was devised by artist Charles Monkhouse on behalf of the Derwent Valley Mills World Heritage Site.
Between October 11 and November 5, the lights will travel down the river from Bleaklow, where the Derwent rises.
They will head to the Trent Mouth, on the other side of Derby.
The visit of the initiative to Chatsworth was welcomed by the Duke of Devonshire.
The Duke said: “For many hundreds of years the Derwent has been an important source of water and food for the people of Derbyshire, as well as a key driver of its trade and prosperity.
“I think this innovative and exciting art project, that travels the length of the county, provides a fitting celebration of the Derwent’s role in the life of so many of our communities.”
Around 1,000 people also watched the light display cascade past from the Three Arched Bridge in the Chatsworth grounds.
The scheme is taking place over the course of a lunar month, with the lights travelling from the source of the river to its mouth.
Local communities along the route have been taking part in special events as it passed by their towns and villages.
The Derwent Pulse is being supported by the Arts Council for England and the Peak District National Park Authority.
It is taking place ahead of next year’s Made in Derbyshire campaign, which will celebrate the county’s culture and heritage.
