Birdcage Walk by St. James's Park takes its name from an aviary which has been here from the time of James I. A continuous line of cages lined the walk when Charles II. was king, and the "Keeper of the King's Birds" was an important official. In York Street to the south of Birdcage Walk, where the Queen Anne Mansions are to-day was the house to which Milton removed in 1651. The street was called Petty France then, from the number of French Protestants residing there. In this house Milton became blind. Here his wife died leaving three daughters, and later while still living here Milton married Catherine Woodcock in 1656. A century and a half later Hazlitt came here to live and set up a stone on the house-side: Sacred to Milton Prince of Poets In the wainscoted room where Milton had often pursued his meditations Hazlitt visited with Charles and Mary Lamb, Hayden and a host of others. York Street was finally named in honour of the son of George III., Frederick, Duke of York. In St. James's Park, where Buckingham Palace stands to-day, Buckingham House was built in 1703 by order of John Sheffield, Duke of Buckingham. Later it was given to Queen Charlotte by George III. to replace Somerset House as a royal residence. Remodelled in 1825 it became the present Buckingham Palace, the town residence of the King. The eastern façade facing St. James's Park was added in 1846. Separating the private grounds of Buckingham Palace from Green Park is Constitution Hill, and in this road leading from the Palace to Hyde Park Corner attempts were made to assassinate Queen Victoria in the years 1840, 1842 and 1849 by lunatics of various degrees. The first building to the east of Hyde Park Corner is Apsley House, built in 1785, presented to the Duke of Wellington by the Government; where he dined the survivors of the Battle of Waterloo every year until his death. The much famed Elgin Marbles now in the British Museum when first brought to London in 1803 from the Acropolis at Athens were placed in Gloucester House in Piccadilly opposite Green Park. Lord Byron spoke irreverently of these relics and their home, calling it the: General mart For all the mutilated blocks of art. Aristocratic Park Lane in early days was a narrow path called Tyburn Lane leading to Tyburn, the place of execution. It is still a narrow way, but to-day lined with splendid houses and crowded with the carriages of rich and fashionable Londoners. Out of Park Lane leads Hertford Street, full of memories of persons of note who have lived there. A tablet on the house at No. 14 indicates that it has been the home of Dr. Jenner, the discoverer of vaccination. Other dwellers in the street were Richard Brinsley Sheridan, dramatist and politician, who lived several years at No. 10, and Sir Edward Bulwer Lytton, novelist, whose house was No. 36.
