Tavigny Castle dates to th late Middle Ages, and it may have been only a refuge tower that is now the central part of the castle. Its walls are long 10 meters, thick 2 meters and they had plenty of arrow slits. The lordship of Tavigny belonged at first to a family who wore already its name, but in 1360, it was already owned by the Ouren family, a powerful Middle-age family from the dutchy of Luxembourg. The central tower that was enclosed in walls with round towers in the corners got transformed little by little in a seignorial residence. The narrow windows and the arrow slits got substituted by large great picture windows and they made a very nice Louis XIII style ensemble
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.
