J. P. Morgan spent three months of every year in [[London]] and owned two houses there. His 'town' house, [[14 Prince's Gate, London|13 Prince's Gate]], was inherited from his father and was later expanded by the acquisition of the neighbouring Number 14 to house his growing art collection. After his death the merged houses were offered to the US government for use as the residence of the [[List of ambassadors of the United States to the United Kingdom|US Ambassador]], from 1929 to 1955. His other property was Dover House, [[Putney]], which was later demolished and developed into the [[Dover House Estate]].{{citation needed|date=July 2022}}
