The National Monument of Scotland, on Calton Hill, is Scotland's national memorial to the Scottish soldiers and sailors who died fighting in the Napoleonic Wars. It was intended, according to the inscription, to be 'A Memorial of the Past and Incentive to the Future Heroism of the Men of Scotland'.
The monument dominates the top of Calton Hill, just to the east of Princes Street. It was designed during 1823-6 by Charles Robert Cockerell and William Henry Playfair and is modelled upon the Parthenon in Athens. Construction started in 1826 and, due to the lack of funds, was left unfinished in 1829. Subsequent attempts to 'complete' the National Monument have never borne fruit for reasons of either cost or lack of local enthusiasm.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
