The first castle in Głogówek was built by the Piasts from the Opole line probably in the 13th century. In the years 1532-1561, the Zeidlitz family took the castle over from the previous owners; in 1561 it was in possession of the Oppersdorffs. They decided to demolish the Gothic building and replace it with a Renaissance structure which has survived - only with minor transformations - to the present day.
The first project was the upper castle with the duke’s chamber and corner towers (1561-1606); from 1606, the lower castle was developed along with a chapel. In the years 1743-1781, the sough wing of the lower castle was expanded and Baroque detailed were added; in the mid-19th century, part of the castle was rebuilt under the supervision of an architect named Gluck.
During the Swedish invasion in 1655, the castle was home to King Jan Kazimierz and his court, and in 1806 it was visited by Ludwig van Beethoven fleeing from the Napoleon’s army.In 1945 the last member of the Oppersdorff family left the castle which has ever since changed hands and has served different functions: youth hostel, regional museum, art gallery, and culture centre. Today, the building is owned by the municipality again and restoration works are underway.

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.
