Wales is famous for many things including its national sport - rugby, historic castles (it has the most castles per land mass in Europe), coal mining, natural beauty and male voice choirs. Singing is a proud part of Welsh culture and it has produced some of the world’s most distinctive voices – including Shirley Bassey and Tom Jones. But it’s also produced some globally famous actors, like Richard Burton, Catherine Zeta-Jones and Anthony Hopkins – as well as the celebrated poet, Dylan Thomas.
