The Barbican Centre is London's ugliest building, according to a new survey.
The Barbican cost £153m to build
The Grade II listed arts centre in central London beat Centre Point Tower and the M16 building to top the poll, which marks the launch of the London Design Festival.
Home to the Royal Shakespeare Company until May 2001, the Barbican complex's labyrinth of tunnels can make it hard to navigate.
It was devised in the 1960s and built in the 70s at a cost of £153m.
When the Queen finally opened it in 1982 she pronounced it "one of the wonders of the modern world".
But it is among a list of London buildings criticised as "dreary and unimaginative" by Grey London, which commissioned the survey.

Chief executive officer Gary Lace said: "Well-designed buildings enhance the urban environment and make working and living in London a richer experience."
The Post Office Tower, which was given Grade II listed status earlier this year, came second in the poll.
And other more recent developments such as St George's Wharf, in Vauxhall, south London, the MI6 building also in Vauxhall and the Millennium Dome in Greenwich, south-east London also made the top 10.
As a part of the design festival, Grey London's central London offices have been redesigned by students from the Central St Martin's College of Art and Design.
