The Land Titles Building was a federal government office built in Edmonton in 1893. It later became the Victoria Armoury, and was used by three Edmonton regiments. It is "likely the oldest existing Land Titles Office in Alberta, one of the oldest extant buildings in the province, and certainly the first purpose-built registry office". At one point federal government attempted to move its offices across the river to the rival settlement of Strathcona, but an angry mob sabotaged the effort and there was an armed standoff with the North-West Mounted Police.
