St. Nicholas' Church (Niguliste kirik) is a medieval church in Tallinn. The church is dedicated to Saint Nicholas, the patron of the fishermen and sailors. It was founded and built around 1230-1275 by Westphalian merchants, who came from Gotland in the 13th century. While the city was still unfortified, the church had heavy bars for closing the entrances, loopholes and hiding places for refugees. When the fortifications around Tallinn were finished in the 14th century (the town wall enclosed the church and the settlement in 1310), the St. Nicholas' Church lost its defensive function and became a typical medieval parish church. There are only a few parts of the original church that have been preserved through the present.
In 1405–1420 St. Nicholas' church obtained its current appearance, when the central aisle was built higher than side aisles and the church was redesigned as a full basilica. In 1515 the tower was built higher and covered with late-Gothic spire. In late 17th century the tower was strengthened and secured. The spire was replaced with a Baroque spire with airy galleries, which was raised higher stage by stage through several centuries. The tower is now 105 metres high.
Saint Nicholas was the only church in Tallinn which remained untouched by iconoclasm brought by the Protestant Reformation in 1523 (or 1524). The head of the congregation poured molten lead into the locks of the church, and the raging hordes could not get in.
The church was partially destroyed in Soviet Bombing of Tallinn in World War II. After restoration it is in use as an art museum and concert hall. Most famous of the artworks is a painting Danse Macabre (Dance of Death) by the Lübeck master Bernt Notke, which depicts the transience of life, the skeletal figures of Death taking along the mighty as well as the feeble ones. Only the initial fragment of the original 30 metres (98.4 ft) wide painting (accomplished at the end of the 15th century) can be seen in the St Nicholas' Church.

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.
