The museum was in <unk> ; prior to the war , construction had begun on a new purpose @-@ built building to house the collections . This had ceased during the conflict and the edifice was left abandoned during Cardiff 's post @-@ war economic slump . Wheeler recognised that Wales was very divided regionally , with many Welsh people having little loyalty to Cardiff ; thus , he made a point of touring the country , lecturing to local societies about archaeology .

Carr , the Wheelers ' work for the cause of the museum was part of a wider " cultural @-@ nationalist movement " linked to growing Welsh nationalism during this period ; for instance , the Welsh nationalist party <unk> Cymru was founded in 1925 .
