Sharon Heal speaks to Marian Gwyn, who has worked to diversify heritage practices throughout her 30-year career in the museum sector, including producing the first exhibition on slavery at any National Trust property in 2007. More recently, with Welsh Government funding, she devised and led a transformative initiative to diversify and decolonise local museums in Wales.
