Monuments, on the verge of collapse

I was at Tate Britain last month for Richard Deacon's solo and the exhibition Ruin Lust when I caught sight of Phyllida Barlow's site specific work Dock being installed in the grand spaces of the Duveen Galleries.  Using inexpensive everyday materials, Barlow's large-scale installations embrace mess, absurdity and precariousness while contrasting sharply with the monumental spaces in which they are placed.  It's a pity I have already left London when Barlow's show opened.  These pictures taken while Dock was still being installed, appearing as if it were on the verge of collapse, are no less interesting than the finished work.
