Paul's Cross was a preaching cross and open-air pulpit in St Paul's Churchyard, the grounds of Old St Paul's Cathedral, City of London. It was the most important public pulpit in Tudor and early Stuart England, and many of the most important statements on the political and religious changes brought by the Reformation were made public from here. The pulpit stood in 'the Cross yard', the open space on the north-east side of St Paul's Churchyard, adjacent to the row of buildings that would become the home of London's publishing and book-selling trade.
