When renovating an old house, do not be surprised if you find an old shoe. These shoes were placed in walls, under floorboards or behind chimneys to ward off evil spirits. The shoes are well worn and usually not in pairs. This is only a part of the culture of folk magic that came to Australia in the period from 1788 to 1935 with the convicts and settlers.
Shoes were believed to have powerful anti-ghost properties and explains why they are found in so many old homes under floorboards.
