Buxton Museum and Art Gallery is preparing to re-open its doors following a £1.5m refurbishment.
The Terrace Road museum has been undergoing a major redevelopment programme for the last eight months.
On June 6, the public will be able to see most of the changes for themselves and see what other work is due to be completed.
Councillor Barry Lewis, leader of Derbyshire County Council, said: “It will be very exciting to see the changes taking place now the museum and art gallery is open.”
The biggest alterations are to the museum’s foyer where visitors will be met, can find out more about Buxton and buy souvenirs in the shop.
A lift takes people to the new Wonders of the Peak – a Journey through Time and Place. Work here to clean and mount almost 1,200 objects is still ongoing. These have been selected from the geology, archaeology, history and art collections, with more objects arriving on loan from the British Museum, Manchester Museum and Derby Museums Trust.
Over the summer, visitors will see more of the gallery opened up as it takes its final shape before a grand opening in September.
The oldest objects are more than 350 million years old; the newest is a chalice made from Blue John in 2016.
More work is in-hand developing a digital interpretation of the gallery, which will allow people to explore the collections when they are outdoors in the landscape using a mobile phone, or on computers at home or at the library.
Coun Lewis added: “Once complete it will no doubt attract many more visitors to experience this beautiful and historic county.”
Admission is free, although visitors are asked to make a donation.
