The manuscripts were donated to the National Library of Wales in 1934. "Hedd Wyn, Ei Farddoniaeth", a complete Welsh language anthology of his works, was published by Trawsfynydd's Merilang Press in 2012. The poem "Yr Arwr" ("The Hero"), for which Hedd Wyn won the National Eisteddfodd, is still considered his greatest work. The ode is structured in four parts and presents two principal characters, "Merch y Drycinoedd" ("Daughter of the Tempests") and the "Arwr". There has been much disagreement in the past regarding the meaning of the ode. It can be said with certainty that Hedd Wyn, like his favourite poet Shelley, longed for a perfect humanity and a perfect world during the chaos of war. "Merch y Drycinoedd" has been perceived as a symbol of love, the beauty of nature, and creativity; and "Yr Arwr" as a symbol of goodness, fairness, freedom, and justice. It is wished that through his sacrifice, and his union with "Merch y Drycinoedd" at the end of the ode, a better age will come. A bronze statue of Hedd Wyn, dressed as a shepherd, was unveiled by his mother in the centre of the village in 1923. It bears an englyn which Hedd Wyn had written in memory of a slain friend, Tommy Morris. Evans' bardic chair is on permanent display at his family's hill farm near Trawsfynydd. Yr Ysgwrn has been preserved just as it was in 1917 by the poet's nephew, Gerald Williams. In 2012, he was awarded an MBE for his "exceptional contribution" to conserving the heritage of his bardic uncle. The Snowdonia National Park Authority announced on St David's Day 2012 that it had acquired the Grade II-listed farmstead for the Welsh nation. The Authority's objectives are to protect and preserve the site while enhancing the visitor experience in order to share the story of Hedd Wyn. In August 2014, the Welsh Memorial Park, Ypres was unveiled at Pilckem Ridge near Ypres. The war memorial stands close to the spot where Hedd Wyn was mortally wounded in July 1917 during the Battle of Passchendaele. To mark the 100th anniversary of his death, a Bardic chair was made to celebrate the life of Hedd Wyn. It was presented to the Welsh Government at a special service of remembrance at Birkenhead Park in September 2017.
