LONDON — The French urban climber Alain Robert, who calls himself “Spider-Man,” has been barred from climbing any buildings in Britain after scaling one of London’s tallest skyscrapers this past week without ropes — and without permission.

Mr. Robert climbed the 46-story Heron Tower, which is over 750 feet high, on Thursday as the police cordoned off the building, closed roads and ushered away curious gawkers.

He was arrested and appeared in a London court on Friday, where he pleaded guilty to causing a public nuisance and received a 20-week suspended sentence and a fine of 5,500 pounds, or about $7,000. He was also barred from climbing all buildings in Britain “until further notice.”

Mr. Robert, 56, has climbed many of the world’s tallest structures, including the Eiffel Tower, the Empire State Building and The New York Times’s headquarters.
