Ruthin Gaol has launched a series of summer activities for visitors.
The historic gaol has opened a new escape-themed trail, based on real-life escapes from the prison.
The trail includes clues and items around the gaol, with each visitor either getting caught or escaping, depending on the trail chosen.
For younger visitors, there are teddies hidden around the site, waiting to be found.
Visitors will also contribute to a Chain made from recycled materials, helping raise awareness about the reuse of recyclable items.
The aim is for the chain to stretch all the way around the gaol by the end of summer.
Each link in the chain is to be crafted from recyclable plastic bottles, which can be decorated in various ways.
Philippa Jones, heritage site operations and development manager at Ruthin Gaol, said: "All are welcome to come along and explore the gaol in Ruthin this summer.
"Ruthin Gaol is the only purpose-built Pentonville-style prison open to the public as a heritage attraction, and features plenty of interesting history, which is great for the whole family."
It features a wealth of history, with exhibitions and displays to entertain visitors of all ages.
Councillor Emrys Wynne, lead member for Welsh language, culture, and heritage, said: "Ruthin Gaol is a brilliant place for families to go to learn more about their local history.
"Over this summer, there are a number of activities included in the entrance fee, with fun for the whole family."
The gaol is the only purpose-built Pentonville-style prison open as a heritage attraction in the UK.
The summer activities at Ruthin Gaol are included in the standard admission price.
