West of Hagley Park, Riccarton is best known for the early Scottish settlers' homes of the Deans brothers - who were in Christchurch before the English arrived - and named the Avvon river after a stream in Scotland. Some original native forest can still be seen at Deans' Bush. Christchurch Boys' High School was built on land purchased from the Deans family, and Christchurch Girls' High School, erected on a former mill site alongside the Avon River. Just upstream is Mona Vale with its popular rose garden. Further west is the University of Canterbury's Ilam campus with its world-renowned rhododendron gardens that flower in October and November. Hornby has cinemas and is the site of November's annual Agricultural and Pastoral Show where country comes to town for three days. At Addington, one of Christchurch's oldest suburbs the WestpacTrust Centre offers a multi-sport facility and Addington Raceway hosts the prestigious New Zealand Trotting Cup. Riccarton is also home to the (largest in Chch) mall - Westfield.
