Countless commuters walk past the former Yates's pub on Moorfields every day - but some may wonder why there is a giant hole cut into the building.
Back in 2007, when Liverpool was European Capital of Culture, a temporary artwork was installed at the former Yates's Wine Lodge.
'Turning the Place Over', created by Richard Wilson, saw an eight meter diameter ovoid cut out of the building fixed on a giant pivot.

When the ovoid, which weighed 26-tonnes, rotated and offered a glimpse into three floors of the building.
The artwork was only supposed to be on display for one year, but kept turning until 2011 due to the phenomenal response.
At the time Richard Wilson said he hoped it could be switched back on or find a permanent home elsewhere.
He told the ECHO: "I came up with the idea in 2004 or 2005. I saw Lewis Biggs, director of the Liverpool Biennial and said 'I've had this fantastic idea, it would be great to do it in Liverpool'.
"I sent him my ideas and the next day he said 'Get up to Liverpool and have a look for a building'!"
The team settled on empty Cross Keys House, opposite Moorfields Station, because it was then owned by the council.
It became a major part of Liverpool's Capital of Culture public arts programme, stunning visitors and passers-by and become a star of YouTube even before it launched.
Turning the Place Over cost £450,000, with Liverpool Culture Company paying £150,000, and was described as “the most daring piece of public art ever commissioned in the UK”.
At the time Lewis Biggs, director of Liverpool Biennial, said it would be "remembered and celebrated for as long as people’s jaws are capable of dropping" - and Mr Wilson said it had not been forgotten.
He said: "I still get people from around the world, curators, people from magazines, people writing books, requesting photos.
"It was a very powerful piece. It took the derelict and the forlorn and forgotten and written off during that year and showed how the power of art can transform it."
