[5] Chief Executive of Cardiff and Vale UHB Len Richards confirmed that the health board had carried out modelling and predictions of patient number scenarios, aided by research from Imperial College, London.

As a result of that research, they felt it necessary to expand capacity in the Cardiff and Vale of Glamorgan area through a large field hospital.

[7] The project involved £8m in capital spending from Welsh Government,[8] and involvement from Cardiff Council, Cardiff and Vale University Health Board, the Welsh Rugby Union (WRU), the Millennium Stadium, and NHS Wales.

[10] The first 330-bed spaces were completed on 11 April, and handed over by the Main Contractor, ES Global Ltd, to the client, Cardiff and Vale University Health Board.

[2] Facilities available include mobile X-ray and CT scanners, and the stadium has opened both the playing surface and directors boxes for use as treatment space.

[12] Cardiff Arms Park was being utilised as part of the Dragon's Heart Hospital and had seen flooring laid upon the artificial turf.

[18] In November 2020, Cardiff and Vale University Health Board (UHB) formally left Dragon’s Heart Hospital.
