Islamabad's architecture is a combination of modernity and old Islamic and regional traditions. The Saudi-Pak Tower is an example of the integration of modern architecture with traditional styles. The beige-coloured edifice is trimmed with blue tile works in Islamic tradition, and is one of Islamabad's tallest buildings. Other examples of intertwined Islamic and modern architecture include Pakistan Monument and Faisal Mosque. Other notable structures are: Secretariat Complex designed by Gio Ponti, Prime Minister's secretariat based on Mughal architecture and the National Assembly by Edward Durell Stone.
