The ducal Widow's Palace in Plön was the widow's seat of the Duchess Dorothea Christina (Dorothea Christine). During its history the building has also served as an orphanage and was modified several times. Today it houses Plön's district museum.
The Widow's Palace was originally a stately home dating to the Middle Ages, which was mentioned for the first time around 1385, and was a fief of nearby Plön Castle. The original building was renovated around 1540 and was used for various purposes, during the rule of the dukes of Plön, including acting as an orphanage from 1685. From 1756 it was extended to become the widow's seat for Dorothea Christina, the mother of Duke Frederick Charles. In the 19th century the court apothecary was moved to the palace. Since the 20th century the building has housed the district museum for the district of Plön.
The barrel-vaulted basement of the palace dates to 1540, after when the building was converted and extended several times. Other alterations to the structure were made in 1639 and 1685, but it was given its present baroque style largely around 1756, although the front was redesigned around 1842 in the classicist style. The palace is a two-storey building under a high mansard roof. It has nine wings and a plastered façade facing the town; its other elevations are in brick. The interior character is that of the 19th century transformation; on the upper floor, the rococo ballroom of 1756, which faces the garden, has been preserved.
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.
