The earliest fortifications in Pillau were made in 1550, when it was an important port of the Duchy of Prussia. During the Thirty Years' War, the Swedes occupied the harbour in the aftermath of their victory over the Polish-Lithuanian Commonwealth. King Gustavus Adolphus landed there with his reinforcements in May 1626. After the ceasefire of Altmark (1629) the Swedes retained Pillau and set out upgrading its fortifications. They constructed a star fort which remains one of the town's landmarks. The final completion of the fortress was made by Prussians in 1670.
In June 1807 Pillau was stormed by Napoleon's Grand Army. No outstanding events took place during the rest of the 19th century. Records of a Scottish 'Colony' established here in 1815 appeared in a 1890 Publication, although their authenticity is questionable.
The lighthouse was built up to a height of 31 meters, and the entire fortress was updated and rebuilt by the Prussians in 1871. Currently it is holding a naval museum.
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.
