Providing essential knowledge about the British capital's built environment, these two volumes cover a large portion of the parish of St. Marylebone, bounded to the south by Oxford Street and to the north by the Marylebone Road, and stretching from just west of Marylebone High Street to the parish boundary along Cleveland Street near Tottenham Court Road to the east.  This area is rich in historic buildings and includes some of London's most celebrated addresses, including Portland Place, Cavendish Square, and Harley Street.  Among the most important buildings covered in this superbly illustrated book are Robert and James Adam's development of Portland Place, where the Royal Institute of British Architects' headquarters is a notable 20th-century insertion.  Other landmarks include Marylebone Parish Church, All Saints Margaret Street and All Souls Langham Place, and the vast, recently demolished Middlesex Hospital.  In addition to new photography, this volume includes meticulous architectural drawings and detailed coverage of the topography.
