The Befreiungshalle (Hall of Liberation) is a neoclassical monument on the Michelsberg hill above the town of Kelheim. It stands upstream of Regensburg on the river Danube at the confluence of the Danube and the Altmühl.
King Ludwig I of Bavaria ordered the Befreiungshalle to be built in order to commemorate the victories against Napoleon during the Wars of Liberation that lasted from 1813 to 1815.
The construction was started in 1842 by Friedrich von Gärtner in a mixture of Neoclassical and Christian styles. It occurred on Michelsberg, in a place previously occupied by a part of the ruins of a pre-historic fortification or town, thought by some to have been Alcimoennis. At the behest of the King, Leo von Klenze later altered the plans and completed the building in 1863.
The powerful-looking rotunda made of Kelheim limestone rests on a three-tier base, which is designed as an octadecagon. The outer facade is divided by 18 pillars with 18 colossal statues by Johann Halbig as allegories of the German tribes that took part in the battles. These are: 'Franconian, Bohemian, Tyrolean, Bavarian, Austrian, Prussian, Hanoverian, Moravian, Saxony, Silesian, Brandenburger, Pomeranian, Mecklenburg, Westphalia, Hesse, Thuringian, Rhinelander, Swabia' (circulating in this order with an arbitrary start).
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.
