This is The Brodsky Pavilion

Pushkin House Pavilion - 101st km – Further, Everywhere, is a temporary pavilion to celebrate Russian poetry in exile. 

• The pavilion was developed with Pushkin House and Russian artist Alexander Brodsky and celebrates the power of the word and the individual voice. 
  
  The 101st km, a concept well known in Russia, refers to the distance that many poets and others were forced to maintain from major cities, often after returning from the labour camps – a kind of internal exile and attempt by the authorities to suppress them.
  
  The pavilion creates a refuge for these voices, which passers-by are invited to enter and experience.
