The Lake Isle of Innisfree
Ireland, the Great!
While Yeats lived in many different places over the course of his life (and he spent huge chunks of time in London), he always considered Ireland home. He was plenty conflicted about the messy political situation in his home country, but it never broke his attachment to it. Many of his poems highlight different (especially rural) parts of Ireland, and "The Lake Isle of Innisfree" is probably the most sincere and personal account of his bond with his homeland.
