  Speaking about his time there, Weiwei said he could "never have imagined conditions like this".
  The Chinese artist's exhibition, Ai Weiwei at Cycladic, will remain open until October.
  The exhibition, at the Museum of Cycladic Art in Athens, includes an huge collage of 12,030 small pictures taken on the artist's camera phone, documenting his time in Lesbos.
  "It is such a beautiful island - blue water, sunshine, tourists - and to see the boats come in with desperate children, pregnant women and elderly people, and they all have fear and they all have it in their eyesâ€¦ You think, how could this happen? I got completely emotionally involved," he said.
  Ai Weiwei, who is 59 years old, became well known in 2011 when he was detained by the Chinese authorities for 81 days during a crackdown on political activists.
  The artist is also planning a feature-length documentary about the refugee crisis.
  "I want it to be a historic account of the tragedy which years, decades, later people will watch and see how we behaved in this moment," he said.
  Ai Weiwei at Cylcadic is the artist's first ever exhibition to be displayed in Greece, and closes on 30 October.
