Come Hell or High Water, a monthly event that takes place on the Thames foreshore at low tide Come Hell or High Water, a monthly event that takes place on the Thames foreshore at low tide. Filippos Tsitsopoulos. A pocket of resistance with performances on the banks of the River Thames by Canary Wharf, a place that exists between water and land, private and public space, wealth and poverty, past and present, and an unknowable future. Where the tide slowly recedes, and a small foreshore is temporarily exposed, Sunday 16th February, 2020.
