Dr Cai Parry-Jones, author of a book on Wales’s Jewish communities, said the country lacked a permanent building dedicated to its Jewish history.
He suggested that an unused synagogue — the oldest in Wales — in Merthyr could be used as a museum or heritage centre.
Speaking to the BBC, Dr Parry-Jones said: “Since devolution, more is being done because Wales is starting to understand and see itself as a multifaith and multicultural country. More could be done.”
The Merthyr synagogue has not been used for worship for years, is for sale, and could be turned into flats.
