Kufstein fortress is one of the most impressive medieval constructions in Tyrol. It is located on a hill rising above the city of Kufstein. This fortress has already been built very early in order to control the entrance from the Alpine foothills into the Inntal valley. However, it has been mentioned for the first time in 1205 AD, when it was in possession of the bishops of Regensburg. In 1415 it was reinforced by Louis VII, Duke of Bavaria.
In 1504 the city and the fortress were besieged and conquered by Emperor Maximilian I. Maximilian had the massive round tower built between 1518 and 1522, substantially adding to its defensibility. From 1703 to 1805 it was a Bavarian possession, returning to Austria in 1814. The fortress acted as prison for a number of political dissidents during the Austro-Hungarian empire.
Today it houses the City Museum of Kufstein. Part of it is also used for concerts and meetings.
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.
