An Iraqi man filmed video footage of potential targets for a terrorist attack on London, a court was told.
Big Ben was featured on the video seized by police
Big Ben, the Houses of Parliament and the London Eye were among the sights on tapes made by Rauf Mohammed, Woolwich Crown Court heard on Tuesday.
The recordings could be of use to someone "angered" by the West's action in his homeland, prosecutors said.
Mr Mohammed, 26, of Glenparke Road, Forest Gate, east London, denies making and possessing articles for terrorism.
He told police the two videos seized were "harmless" tourist souvenirs.
"He said he was a peace-loving man who admires our country's values," prosecutor Paul Taylor told the jury.
But counsel said: "Anyone planning an attack - a rocket attack or suicide bombing - needs to know the layout of his targets."
He told the court: "This is not a tourist video. Its purpose was to help terrorists plan and carry out an attack on our capital."
Mr Taylor said there were also images of Paddington Green police station which was "not the most beautiful of London buildings but a building of special interest to terrorists."
The court heard the footage was probably shot around the autumn of 2003.
The prosecutor said some of the filming was done at night by an unknown cameraman as Mr Mohammed drove around London listening to music about martyrdom and killing Jewish people.
At one point the cameraman was heard to speak of "bombing operations," Mr Taylor said.
He alleged Mr Mohammed's response was to say he hoped Tony Blair, George Bush, Silvio Berlusconi and Donald Rumsfeld would all be "slayed".
When interviewed by police after his arrest, however, Mr Mohammed said the remarks were made when "I was younger" and described them as silly.
He said he was not anti-Semitic.
One of the videos included a 2003 speech by Al-Qaeda leader Osama bin Laden, in which he discussed the current conflict in Iraq.
Mr Taylor told the jury: "You have to decide whether he kept this because he believed what Osama bin Laden was saying."
He said Mr Mohammed was kept under surveillance by MI5 officers in 2004.
The trial continues.
