Horace Walpole, 4th Earl of Orford in the context of "The Castle of Otranto"

St Paul's Church is a Church of England parish church located in Bedford Street, Covent Garden, central London. It was designed by Inigo Jones as part of a commission for the 4th Earl of Bedford in 1631 to create "houses and buildings fit for the habitations of Gentlemen and men of ability". Initially serving as an auxiliary chapel for the St. Martin-in-the-Fields parish, it was raised to a parish church with a dedication to Saint Paul in 1646, as the Covent Garden district expanded. The church is nicknamed "the actors' church" by a long association with the theatre community, particularly in the West End.

Completed in 1633, St Paul's was the first entirely new church to be built in London since the Reformation. Its design and the layout of the square have been attributed to Inigo Jones since the 17th century, although firm documentary evidence is lacking. According to an often repeated story, recorded by Horace Walpole, Lord Bedford asked Jones to design a simple church "not much better than a barn", to which the architect replied "Then you shall have the handsomest barn in England".
