Chorley’s historic Astley Hall will undergo a glowing transformation this weekend.
More than 200 candles and LED spotlights will be used to illuminate the building for two nights.
It is part of the national Museums At Night festival, which is held each year.
The spotlights and candles will focus on paintings, tapestries and furniture, allowing visitors to discover new and interesting features.
There will be music and mystery objects, plus members of the Friends of Astley Hall group will be dressed in costumes.
The lights will be on from 5.30pm to 10pm on Saturday and Sunday.
Chorley Council’s director of people and places, Jamie Carson, said: “If you’ve never been and had a look around Astley Hall or you’ve only ever visited during the day, this is a fantastic opportunity to see the hall and the many treasures it holds in all its glory.
“This event only happens once a year and we wanted to create a special experience for visitors.
“The effect the spotlights and candles have on the hall is magnificent and is definitely worth seeing, so bring the whole family along to the event.”
The Museums at Night festival is an annual weekend of late openings and special events taking place in museums, galleries, libraries and archive and heritage sites all over the UK.
