With its commanding position alongside the River Moselle, located at the junction of the three main Roman roads and at the end of the Trans-Burgundy highway, Châtel played a strategic role throughout its long history up to 1940-44 during World War II.
From the year 1072 until 1373, it belonged to the Earls of Vaudémont, related to the House of Lorraine. It then became the property of a most prominent Burgundian family, the Lords of Neufchâtel, after the wedding of daughter Alix de Vaudémont with Thiebaut VII of Neufchâtel-Burgundy.
It became the centre of a wide territory which supported the Burgundian cause for years. In 1544, the House of Lorraine gained possession of Châtel, thus ending a legal wrangling between Elisabeth of Neufchâtel's heirs. Then the fortress stood up against the French invasion during the Thirty Years' War and changed hands nine times.
It was finally completely dismantled in 1671 on Louis the XIV's orders.
Built on the edge of a jutting limestone promontory alongside the Mosel River, surrounded by dry ditches 58 m wide, the castle dominated the medieval town and its surrounding walls with its twelve towers and two main gates.
The first structure, built during the 11th and 12th century, showed a single rectangular keep. It was enlarged during the 13th century and further extended in the 15th century to become one of the most important places in the area, with a unique attempt to match the evolving needs of modern artillery.
Two curtain walls, with a total combined length of about one mile (1.4 km), comprised not less than 22 towers. A sophisticated network of storerooms and galleries completed the fortress' defenses and allowed communication between the castle, the town downwards, and the river banks.
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.
