Bleeding Heart Yard is a cobbled courtyard off Greville Street in the Holborn area of the London borough of Camden. The courtyard is probably named after a 16th-century inn sign dating back to the Reformation that was displayed on a pub called the Bleeding Heart in nearby Charles Street. The inn sign showed the heart of the Virgin Mary pierced by five swords (Wikipedia)

64 Bleeding Heart Yard is named after the seventeenth century myth of Lady Elizabeth Hatton, daughter of Christopher Hatton. Legend has it, Lady Hatton made a pact with the devil to secure wealth, position, and a mansion in Holborn. During the housewarming of the mansion, the devil danced with her, then tore out her heart, which was found, still beating, in the courtyard the next morning.
