Work is underway on the £25.5m redevelopment of St Fagans: National History Museum in Cardiff, Wales.

The project, which received £11.5m Heritage Lottery Funding, will see the expansion of its exhibitions, new galleries and open-air demonstrations.

The project includes revamping the main building which will showcase displays exploring life in Wales from the earliest humans to today.

New galleries will also be added that look at three aspects of St Fagans history including: when and why Wales became a nation; details of people’s day to day lives, through the ages; and a gallery where guests can learn the creative skills of generations of craftspeople.

The archaeological experience will extend out into the open-air site and will recreate Llys Rhosyr, one of the courts of the Princes of Gwynedd, where school children can stay overnight.

Other facilities include activity and event spaces, an auditorium, a dedicated research space where visitors can study the collections and a café.

On the site there will also be a new eco-friendly building with facilities for craft workshops and open-air performances.
