On December 6, 1917, the biggest man-made explosion prior to the atom bomb occurred in Halifax Harbour. Halifax was a booming port involved in the World War I effort, but on that December morning the Mont-Blanc, loaded with munitions bound for the war in France, collided with the Imo. The end result was an explosion that devastated the city. Buildings were flattened, more than a thousand people were dead by the end of the day, a thousand more would die before it was all over, and nine thousand people were left injured.

The Hydrostone area was built as relief housing after the explosion. Completed in 1920, it was designed according to the most up to date town planning principles of the time. Constructed of "hydro-stone" concrete blocks, the 325 dwellings were built along realligned streets with wide treed courts. The area was designed by town planner Thomas Adams, and was Canada's first government-assisted housing project. Some more information on the Hydrostone can be found here.
