Sobowidz Castle was built in the second half of 14th century by the Teutonic Order. During the Polish–Lithuanian–Teutonic War it was conquered by Polish, but later returned to Teutonic Order. The castle was mainly destroyed in 1454 when Teutonic Knights surrended. In the 16th century the castle was rebuilt to Governor palace, but it was again destroyed by Swedish army in the 17th century and demolished in 19th century. The current red-brick building was built after that. Today Gothic basement, moat and parts of the wall remain of medieval castle.

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.
