Residents and visitors to Chesterfield can find out more about clocks and time in an exhibition at Chesterfield Museum.
The exhibition, called Time Matters, is in the art gallery at the popular Chesterfield Borough Council–run attraction on St Mary’s Gate until Saturday 28 November.
The exhibition allow visitors to think about "what is time?", the link between Greenwich Mean Time and the railways and the importance of measuring time at sea.
There is a display of clocks and time pieces from the museum's collection with links to Chesterfield, including a clock from Robinson's, a Georgian longcase clock of Thomas Mawkes of Chesterfield and a clock cast at Staveley Works.
Visitors can explore how long they think a minute is as well as different types of clock and also make a simple sextant.
Councillor Amanda Serjeant, Chesterfield Borough Council's cabinet member for town centre and visitor economy, said: "This interactive exhibition also allows our visitors to explore the concept of the time for themselves as well as see some of our objects which are part of Chesterfield’s history.
"It is suitable for all ages and a great way for families to learn together."
Chesterfield Museum is open each Monday, Tuesday, Thursday and Friday from 10am to 4pm.
Admission is free.
