Westminster served as the location of the Gordon Riots of 1780. 

On April 24, 1993, the Irish Republican Army (IRA) detonated a massive truck bomb on Bishopsgate, causing widespread devastation London’s financial district. The attack involved a one-ton bomb hidden in a stolen truck, parked near 99 Bishopsgate. Despite a warning call placed about an hour before the explosion, the bomb caused over £350 million ( with estimates reaching one billion) in damages, one of the most costly terrorist attacks in Britain at that time. This wasn't the first time the IRA had utlied bombs against the British Army.

Liverpool Street Station, constructed between 1864 and 1874, marked a turning point in the transformation of Bishopsgate. It was designed to replace the older Bishopsgate terminus of the Great Eastern Railway. Liverpool station was envisioned as a grand, modern hub that could accommodate the increasing demand for rail travel into and out of the City of London.  The actual railway itself was built ontop of Bethlem Royal Hospital, which focused on care for mentally "ill" patients. Currently, it projects to see about 80 million passengers annually.
