A strange sight on the Thames

As I was walking in this morning, I ws greeted by a strange sight as I neared Tate Modern, and the Wobbly Bridge; Waterloo Pier – a thethered, floating wooden jetty/quai/riverboat stop. So I stopped and took some photos.

I’ve no idea what it was doing there, and from whence it came. There were no notices up about it or on it, and the only other craft on the river were a Police launch (equally mystified by the looks of it as the zoomed off) and the silent yet looming, Damien Hirst decorated, Tate-to-Tate river shuttle.
