Manchester Museum's reopening has been delayed due to "the challenges of the pandemic".
Initially slated for the end of 2022, delays in the construction supply chain mean the institution now plans to reopen to the public in February 2023 following an "ambitious and complex" £15m transformation project.
The building will be 25% larger once construction completes, and include four new galleries: a South Asia gallery, the Lee Kai Hung Chinese Culture Gallery, a "Belonging Gallery" and an exhibition hall hosting Egyptian mummies.
The South Asia gallery will be the first of its kind in the UK, created in partnership with the British Museum.
"Our team and partners have never lost faith in our vision for a reimagined Manchester Museum that is more caring, inclusive and imaginative," Director Esme Ward said.
