A scene from The Park
Art lovers will be invited to "become a voyeur" at an exhibition of infrared photographs showing couples having sex in a Japanese park.
The Park forms part of this year's Liverpool Biennial alongside films, sculptures and live performances.
The photographs taken by Kohei Yoshiyuki caused a storm when they were first shown in Japan more than 30 years ago.
Biennial director Sally Tallant said: "He took photographs of people ... having sex in parks, and when it was first installed it was mainly small photographs in a space and you had to enter the space with a torch, which is how we are going to install it at The Open Eye gallery for its presentation in Liverpool, so you'll become a voyeur."
Other work at the modern art festival includes a lift that appears to be bursting through the floor of the Liverpool One shopping centre and a door guarded by a bouncer and permanently left ajar.
Organisers said the work, called But I'm On the Guest List Too!, was "asking questions about who is and who is not a VIP".
Work will go show inside the Cunard Building - one of the city's landmark Three Graces lining the waterfront - and a "spectacular pavilion" designed by architect David Adjaye will be put up on the Albert Dock.
Landscape architecture firm Field Operations, which designed New York's High Line which turned a disused railway track into a park, will transform Everton Park by planting crops.
Ms Tallant said: "We are thinking about how Liverpool could create a park that's productive in lots of different ways so the beginning of that is it's going to start to grow food in the park."
The event, which runs from September 15 to November 25, attracts more than half a million visitors to the city and contributes £27 million to Liverpool's economy.
Liverpool Mayor Joe Anderson said: "Liverpool Biennial is always a highlight of the city's cultural programme.
"It draws large numbers of people to Liverpool and is a must-see festival for anyone with an interest in art and culture.
"It is thought-provoking, challenging and entertaining and never fails to provoke discussion and debate.
"It is a measure of the cultural significance of our city that we are able to stage an event which is hugely respected by artists, critics and the public."
