Grünwald Castle is a medieval hill castle. The history goes probably back to a Roman watchtower on the Isar river. The high medieval castle of the 12th century was documented as a possession of the counts of Andechs. In 1293 it came into the possession of the Wittelsbach. Louis II, Duke of Bavaria acquired at that time the possession of the fortress from Ulrich Vellenberg, a ministeriales of the Counts of Andechs. The castle served then also as a residence for his consort Matilda of Habsburg. The present building dates mainly from the late 15th century, when the castle was renovated to celebrate the wedding of Albert IV, Duke of Bavaria with Kunigunde of Austria, a daughter of emperor Frederick III. The construction work was carried out 1486–87 under the direction of the foreman Jörg Weikertshausen. Louis X, Duke of Bavaria was born here in 1495. The castle was then used as a ducal hunting lodge, prison and powder magazine.
In 1872 the castle was sold into private hands. A project for a luxury condominium was prevented by a citizens' initiative which finally led to the purchase of the castle by the Free State of Bavaria in 1976. Since 1979 the Castle houses the Museum Grünwald, a branch of the Bavarian State Archaeological Collection. The castle can be visited, the main tower offers a worthwhile view.
Large parts of the castle were demolished in the 17th and 18th century because the Isar River had undermined the castle hill. At that time the late-Gothic residential quarters of the castle with their rich interior and the chapel of St. George were lost. The early modern state is still delivered on a fresco in the Antiquarium in the Munich Residenz.
Since the partial demolition the fortress is an irregular rectangle plant, which is protected by a kennel with a round tower and a deep moat and a gate tower with a renewed cycle of coat of arms. In the north-east corner stands a donjon, a high, square tower. In between lies the elongated three-storey east wing. The north west corner is dominated by the embattled so-called little tower. The adjoining west wing consists of three different levels. The deep fountain in the courtyard which is lined with tufa stone still goes back to the Middle Ages.
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.
