Parts of a display of almost a million ceramic poppies that have filled the Tower of London moat to mark the centenary of World War I will be preserved and go on tour, organizers said.
But there have been calls from politicians and members of the public to keep the installation open longer.
The poppies are due to be removed starting the next day, and sent to people who have bought them in return for donations to military charities.
Each of the 888,246 poppies represents a service member from Britain or its empire killed in the Great War.

Organizers estimate 4 million people will have visited the display by Tuesday, which is Armistice Day, the anniversary of the end of World War I on Nov. 11, 1918.
The temporary installation, titled "Blood Swept Lands and Seas of Red," has generated intense interest, with thousands lining up daily to look since it opened in August.
The poppies were made by hand around the clock at Cummins' workshop in England.
The ceramic flower will be sold from 5th August for £25 to raise money for charities thhat served the armed forces.
Every evening, the names of the military personnel killed will be read out in a Roll of Honour.
The last flower will be planted on 11th November, a day when U.K set aside to commemorate the end of the war.
Each poppy represents a military fatality in World War I. The entire creation will be unveiled on 5th August, exactly 100 years of Britain's involvement in the war.
Crawford Butler, the longest serving Yeoman warder planted the first of the poppies.
“Blood-Swept Lands and Seas of Red” is an installation conceived by artist Paul Cummins and designer Tom Piper.

They eventually will be preserved in the Imperial War Museum.
Cameron said parts of the display, including a "wave" of poppies rising beside an entrance to the centuries-old Tower, would remain until the end of the month before going on a national tour.
Prime Minister David Cameron visited the site Saturday, saying it had become a "much loved and respected monument."
