The Lazy Poets Thursday Haiku

I expect a trio of haiku has a special name and if Bjorn http://brudberg.wordpress.com/ reads I hope he will tell me.

Scorhill circle

Four thousand years past

flourishing on Scorhill Down

ancient settlement

Solid granite rocks

disgorged by volcanic fire

circle hallowed ground

Tall maidens of stone

standing for millenia

sheltering their hearths
