Calton Hill is a large greenspace overlooking the city of Edinburgh. It has several monuments and the observatory. This unfinished colonnade resembling the Parthenon is the most prominent structure. Work on the National Monument began in 1826 and stopped within three years when the funds were depleted. The structure was meant to be a tribute to Scottish soldiers who died during the Napoleonic Wars (1803 – 1815). Across several European countries, an estimated 2.5 million military lives were lost plus an additional one million civilians.
