August 4th 2014 marks 100 years since the outbreak of World War One. Millions of soldiers from Wales and the rest of the UK enlisted to fight in the conflict, which lasted for four years between 1914 and 1918.
A special poppy-shaped garden has been created in Caerphilly to remember those who fought in the First World War. The garden will contain poppies and various other flowers.
It will be officially unveiled today and the garden will serve as a reminder of the centenary of the outbreak of World War One.
People across Wales are switching off their lights for an hour this evening and lighting a candle of remembrance.
