A place that exists ?

Walking back to my flat last night through Waverley station I came out of the back entrance and then , when crossing Calton Road , happened to look up.

I puzzled about what this was / meant for the rest of my journey and then googled it.

And then googled some more.

"In the unrelenting pace of modern life, Katie Paterson grants us permission to pause" says one review.

She did just that tonight - so thanks.
