Memin Gate

Following the Menin Gate Memorial opening in 1927, the citizens
of Ypres wanted to express their gratitude towards those who had
given their lives for Belgium's freedom. As such, every evening
at 20:00, buglers from the local fire brigade close the road which
passes under the memorial and sound the "Last Post". Except during
the occupation by the Germans in World War II when the daily ceremony
was conducted at Brookwood Military Cemetery, in Surrey, England, this
ceremony has been carried on uninterrupted since 2 July 1928. On
the evening that Polish forces liberated Ypres in the Second World War,
the ceremony was resumed at the Menin Gate despite the fact that heavy
fighting was still taking place in other parts of the town.
