Once the largest city-fortress in the entire Republic of Venice, Zadar’s walls allowed it to retain more of its independence than most of its neighbouring cities, and meant that it was never captured by the Turks.
The most impressive gate of the walls was Land Gate - then the main entrance into the city - in the little Foša harbour, built by a Venetian architect Michele Sanmicheli in 1543. It is considered one of the finest monuments of the Renaissance in Dalmatia, and has the form of a triumphal arch with a central passage for wheeled traffic, and two smaller side arches for pedestrians. It is decorated with motifs such as St. Chrysogonus (Zadar’s main patron saint) on his horse, and the Shield of St. Mark (the coat of arms of the Republic of Venice). Previously, the area had been highly defensive, with a surrounding moat.
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.
