The design has a unique aspect that allows the sun to light the interior only on the 11th hour of the 11th day of the 11th month, the anniversary of the armistice that ended the war and the time for the minute's silence on Remembrance Day [REF].
A commemorative ceremony is held yearly in the park on that date, in conjunction with similar ceremonies at the nearby multi-national Menin Gate Memorial in Ypres.
