The important role played by the Poldhu radio station at the outbreak of World War One will be remembered this Monday.

Guests will gather at 11am at the Lizard Wireless Station to mark the declaration of war, which was issued by Whitehall at 11pm on August 4, 1914 and broadcast to merchant ships from Poldhu.

On Monday Helston mayor Mike Thomas will open a special event using the call sign GB100ZZ from the site where the first message was sent – today the home of the Poldhu Amateur Radio Club in the National Trust Marconi Centre.
