The Museum of Lancashire has reopened to the public after being closed for a year for a £1.7m refurbishment.
There is free admission for the first 12 months at the revamped museum in Preston, which has a new entrance.
It has also added to its selection of galleries, with eight new interactive collections covering Roman times, the Iron Age and Edwardian England.
The refurb was paid for with £800,000 of council funding and £920,000 from the Heritage Lottery Fund.
The funding for the work was secured in 2009. The museum expected to reopen in May 2011 but it was held up due to issues with planning permission.
