Notre Dame de Lorette, also known as Ablain St.-Nazaire French Military Cemetery, is the world's largest French military cemetery. It is the name of a ridge, basilica, and French national cemetery northwest of Arras at the village of Ablain-Saint-Nazaire. The high point of the hump-backed ridge stands 165 metres high and - with Vimy Ridge - utterly dominates the otherwise flat Douai plain and the town of Arras.
The ground was strategically important during the First World War and was bitterly contested in a series of long and bloody engagements between the opposing French and German armies. It was the focal point of three battles of Artois (1914-1915). The Battles of Artois were as costly in French lives as the better-known Battle of Verdun. As with numerous other sites across France, Notre Dame de Lorette became a national necropolis, sacred ground containing the graves of French and Colonial fallen, as well as an ossuary, containing the bones of those whose names were not marked.
In total, the cemetery and ossuary hold the remains of more than 40,000 soldiers, as well as the ashes of many concentration camp victims. The basilica and memorial buildings were designed by the architect Louis-Marie Cordonnier and his son Jacques Cordonnier, and built between 1921 and 1927. The first small building was raised in 1727 by the painter Nicolas Florent Guilbert, who had made a successful pilgrimage to Loreto (Italy), to shelter a statue of the Virgin Mary. It was destroyed in 1794, rebuilt in 1816 and transformed in 1880.
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.
