The opening as it stood in 2015
On 15–16 December 2014 a lone gunman, Man Haron Monis , held hostage ten customers and eight employees of a Lindt chocolate café located at Martin Place in Sydney, Australia. Police treated the event as a terrorist attack at the time but Monis' motives have subsequently been debated. After a 16-hour standoff, a gunshot was heard from inside and police officers from the Tactical Operations Unit stormed the café. Hostage Tori Johnson was killed by Monis and hostage Katrina Dawson was killed by a police bullet ricochet in the subsequent raid. Monis was also killed. Three other hostages and a police officer were injured by police gunfire during the raid. Early on, hostages were seen holding an Islamic black flag up against the window of the café, featuring the shahādah creed. Initially, some media organisations mistook it for the flag used by the Islamic State of Iraq and the Levant (ISIL); Monis later demanded that an ISIL flag be brought to him. Monis also unsuccessfully demanded to speak to the Prime Minister of Australia , Tony Abbott , live on radio. Monis was described by Abbott as having indicated a "political motivation" but the eventual assessment was that the gunman was "a very unusual case—a rare mix of extremism, mental health problems and plain criminality". In the aftermath of the siege Muslim groups issued a joint statement in which they condemned the incident, and memorial services were held in the city at the nearby St Mary's Cathedral and St James' Church . Condolence books were set up in other Lindt cafés and the community turned Martin Place into a "field of flowers". The Martin Place Lindt café was severely damaged during the police raid, closed afterwards and renovated for re-opening in March 2015. The Sydney Morning Herald .
