Casa Loma is named after the famous castle. The image of a castle atop the Avenue Road Hill, surrounded by ravines, large old trees, joggers and BMWs is an eclectic mix, considering the neighbourhood is located close to downtown Toronto. In the late nineteenth century South Hill, also in this area, became home to some of the wealthiest citizens of Toronto. They built a series of manors along the top of the hill. The area was annexed to the city of Toronto in a series of sections beginning in 1905. It has remained an expensive residential area, though most of the manors have today either been demolished or converted to other uses. The area is dominated by the steep hill of the former Lake Iroquois shoreline. The southeastern section of South Hill is known as Rathnelly.
