Today, more than 75 million people worldwide call themselves Methodists - but this vast movement had its origins in a humble location in Bristol. Here, John Wesley created a centre for preaching, lodging and welfare. He called it the New Room - and it still operated today, the oldest methodist building in the world. Not far away, the home of his younger brother Charles has also been preserved. Both now stand as part of the story of this global faith, and also as a reminder of life in the 18th century.
