Measuring some 18 metres by 8 metres, Edinburgh's aluminium Olympic Rings are located on The Mound.
The five rings represent the five continents involved in the Olympics and were designed in 1912 by Baron Pierre de Coubertin, the founder of the modern Olympic Games, adopted in 1914 and debuted at the 1920 Antwerp Olympics.
The blue, yellow, black, green and red colours represent the union of the five continents and the meeting of athletes throughout the world at the Olympic Games.
The rings were installed in time for the city’s celebrations when the London 2012 Olympic Torch Relay visited last week.
The London 2012 Opening Ceremony on 27 July 2012 marks the start of the Olympic Games, which last for 16 days.
