Medininkai Castle was built in the late 13th century or the first quarter of the 14th century. The defensive perimeter of the castle was 6.5 hectares; it is the largest enclosure type castle in Lithuania.
The castle was built on plain ground and was designed for flank defence. The rectangular castle's yard covered approximately 1.8 hectares and was protected by walls 15 metres high and 2 metres thick. The castle had 4 gates and towers. The main tower (donjon), about 30 metres high, was used for residential quarters. Medininkai was first mentioned in 1392. The castle was badly damaged by a major fire in the late 15th century. Because of increased use of firearms, this type of castle was no longer suited for defensive purposes and was later used as a residence. In 1655 during the war with Russia the castle was badly damaged and never reconstructed again. During the Second World War Germans set their gun arsenal in one of towers of Medininkai castle. The tower was burst when Germans retreated. The castle was not repaired until 1960. Only then slow reconstruction works were started, however, full reconstruction was not finished until now.
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.
