Septfontaines Castle is one of the castles belonging to the Valley of the Seven Castles. It is not clear when the first castle was built in Septfontaines. In 1192, there is a reference to someone by the name of Tider who was Lord of Septfontaines. In 1233, Jean de Septfontaines placed the property under the protection of Countess Ermesinde of Luxembourg. At the beginning of the 14th century, Thomas de Septfontaines, a friend and companion of Emperor Henry VII, was the lord of the castle. In 1600, Christoph von Criechingen built a huge Renaissance tower at the northern entrance. In 1779, a fire destroyed the castle which increasingly fell into ruin. In 1919, the castle was partly demolished but in 1920 the owners attempted to carry out restoration work but unfortunately did not pay much attention to historical architectural requirements. Today the castle is privately owned and cannot be visited.
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.
