Reuland Castle in Burg-Reuland, near the border of Germany, was probably built after 1148 by the von Reuland nobles. The castle was sold in 1322 to Count John the Blind and the King of Bohemia. On May 24, 1384, King Wenzel of Luxembourg designated Edmund von Engelsdorf the Secretary of the Treasury of Luxembourg, and donated the Castle and the Reuland Domain to him.
The castle's origins can be traced to the 9th and 10th centuries. The entire complex has been modified significantly since then, most importantly to adapt its defences to artillery attacks in the 15th century. Although it was destroyed by French revolutionary troops at the end of the 18th century, it has recently been restored to its former medieval glory.
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.
