Pretoria:
is a city located in the northern part of Gauteng Province, South Africa. It is one of the country's three capital cities, serving as the executive (administrative) capital; the other two being Cape Town and Bloemfontein, respectively the legislative and judicial capitals. Pretoria's main street, Church Street, is the longest urban street in South Africa and one of the longest straight streets in the world. Many of the city's streets are lined with Jacaranda trees that blossom mauve (purplish blue) in spring, giving rise to the city's nickname "Jacaranda City". The Cullinan Diamond (the largest gem diamond ever found) was discovered in the town of Cullinan near Pretoria at the Premier Mine on January 26, 1905.
