Woolwich Crown Court was designed as a high security courtroom and is now the preferred venue for terrorism trials . Formerly , terrorist cases in the London area would be heard at the Old Bailey . Improvements have been made to courtrooms 1 and 2 at the cost of £ 600,000 to enhance their ability to handle complex terrorism trials , particularly those involving multiple defendants . A tunnel links the court to HM Prison Belmarsh , which is a high security prison . This provides a secure route for bringing defendants in high-profile terrorist cases before the court . Armed police can be deployed to provide security . On 15 January 2007 , Woolwich Crown Court began hearing the trial of the six men accused of attempting the 21 July 2005 London bombings on the London transport network . It is also the venue for the trials of those charged with offences from the 2006 transatlantic aircraft plot and the Hatton Garden safe deposit burglary in 2015
