Christchurch Botanic Gardens.
Work began on the Christchurch Botanic Gardens in July 1863, when an English oak tree was planted to commemorate the marriage of Queen Victoria's eldest son Prince Albert Edward to Princess Alexandra of Denmark. Over the years, natural wetlands and sand dunes have been transformed into an elegantly cultivated 30 hectare park with more than ten sub-gardens, which are mostly contained within a loop of the Avon River.
