Blankenhain Castle is a large castle in Blankenhain near Crimmitschau. The castle dates back to the 12th century. It is first documented in 1423 as Wasserburg. Half of it burned down in 1661 and was rebuilt in 1699 (some sources say 1700). In 1765 the castle acquired its current Baroque appearance with mansard roof and domed towers. After World War II, the Soviet regime ordered the castle destroyed, but it was saved by the intervention of courageous locals. Since 1981, the castle and the surrounding land have been developed as an open-air museum of agriculture and rural life in central Germany between 1890 and 1990. The museum covers 11 hectares, including 60 buildings.

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.
