Osterley Park

The origins of Osterley Park date back to 1562, when Sir Thomas Gresham, a financial advisor to Elizabeth I, had the estate built in the Tudor style. In 1711, the banker and then Lord Mayor of London, Sir Francis Child, acquired the property. His grandson, also named Francis Child, commissioned the architect Robert Adam in 1761 for a redesign of the mansion. Adam added a portico with tall double columns to the central part of the existing red brick building and its four corner towers, as well as a double-flight grand staircase on the park side.
