Dee1, I believe there's Yeats' museum in Sligo... Tread gently for you are treading on my dreams!

I am an Irish woman how I love his poetry.He is buried in Drumcluff With the flat topped mountain of Ben Bulbin over looking Sligo Tow

Some of Yeats' poème should have benn mentioned, such as "the second coming", "easter", "the stolen child", "when you are old", and so on.
