vesselArtists Louise Ashcroft and Fritha Jenkins will re-activate the lost River Westbourne by staging a sculptural procession between Paddington Basin and the River Thames.

Samples of water found at sites en route will be added to a large, boat-like vessel and carried along the river's former course. Swishing and splashing through Kensington and Chelsea, the collected waters will mix together, echoing the mysterious Westbourne which now runs deep below the streets in an underground pipe. Canal water, holy water, lake water, fountain water, designer bottled water; each source will be reflected upon by an artist, musician or academic whose practice relates to its site. Revellers are invited to join the procession and help with the filling and carrying of the vessel.

The journey will culminate in Chelsea, where the contents will be poured over the beach into the Thames.
