The Prince Room was prepared at Craigs Royal Hotel for his stay. The city's first civic centre—Prince Alfred Hall—erected over the Yarrowee between the two municipalities, was named in his honour during his visit. The later attempt of the Prince's assassination by Ballaratian Henry James O'Farrell was met with shock and great horror from locals. Ballarat was proclaimed a city in 1871. Gong Gong reservoir was built in 1877 to alleviate flooding and to provide a permanent water supply. A direct railway to Melbourne was completed in December 1889. Many industries and workshops had been established as a result of manufacturing and servicing for the deep lead mining industry. Local boosterists at the start of the 20th century adopted the nickname "Athens of Australia", first used to describe the city by the prestigious Irish-Australian jurist and politician of the early 20th century Sir John Madden. On 13 May 1901, the Duke of York (later George V) and his wife, Mary the Duchess of York, travelled by train from Melbourne to Ballarat. The first electricity supply was completed in 1901 by the Electric Supply Company of Victoria. A bluestone power station was built at the corner of Ripon Street and Wendouree Parade in 1901 with the main aim of providing the power required for electrification of the city's tramway network. Following the start of the 20th century, however, mining activity slowed and Ballarat's growth all but stopped—the city went into a period of decline and saw a reversal of the fortunes acquired in the previous century. The Sunshine rail disaster in 1908 resulted in the death of dozens of Ballarat residents. On 19 August 1909, a great storm lashed the city, resulting in the death of one person and injury of seven others. During the storm, a tornado swept across the city's northern and eastern suburbs destroying numerous homes in Ballarat North, Soldiers Hill, Black Hill and Ballarat East, lifting and then again touching down at Eureka where it destroyed more homes before dissipating. Ballarat's significant representation during WWI resulted in heavy human loss. The city eventually lost first provincial status to Geelong. In response, local lobbyists continually pushed the Victorian government for decentralisation, the greatest success being the Victorian Railways opening the Ballarat North Workshops in April 1917. The Great Depression proved a further setback for Ballarat, with the closure of many institutions and causing the worst unemployment in the city's history, with over a thousand people in the dole queue. The city's two municipalities, Ballarat East and West Town Councils, finally amalgamated in 1921 to form the City of Ballarat.
