National Museum Cardiff Weighs Temporary Closure as Redevelopment Plans Advance
National Museum Cardiff may temporarily close while Amgueddfa Cymru reviews options for maintenance and redevelopment at the historic Cardiff institution. The museum, which is approaching its centenary next year, is now at the center of a consultation process that could shape how one of Wales’s most important cultural sites operates for decades to come.
Amgueddfa Cymru said any decision to shut the museum for a period would follow “a full review and consultation.” In a statement, the organization said it is examining ways to “maintain and preserve the building” while also improving the visitor experience so the museum remains “fit for purpose for future generations.”
The move comes after Amgueddfa Cymru appointed a design team — AHR and C.F. Møller Architects — to carry out enabling works tied to maintenance. According to the organization, those works would place the museum in the “best possible position” for wider redevelopment if that proceeds.
The Public and Commercial Services union, or PCS, said it is in discussions about the impact on staff, the protection of collections, and the museum’s future operation. The union added that it would be premature to speculate on how long any closure might last or what it would mean for members.
The possibility of closure is not new. In 2024, chief executive Jane Richardson warned that the museum could shut if more funding was not secured to repair the deteriorating building. She pointed to water ingress and failing electrics as signs that the building’s future was already under strain. At the time, then culture secretary Lesley Griffiths said the museum would not close and that the Welsh government was considering specific funding over the following years.
Pressure on the building has continued. In February 2025, National Museum Cardiff closed for several days because of building maintenance and health and safety concerns. The museum has also benefited from public support: for the 2024–25 financial year, the Welsh Government allocated £30.5 million in grant-in-aid to Amgueddfa Cymru, according to Audit Wales. That was supplemented by a £940,000 boost in September 2024, and by an additional £3 million announced in May last year for urgent works at the National Library of Wales in Aberystwyth and Amgueddfa Cymru, with National Museum Cardiff a focus.
The question now is less whether the building needs intervention than how far that intervention will go. With Wales’s national museum approaching 100 years, the decision will test how the country balances preservation, public access, and the cost of keeping a major heritage institution open.
