St. Michael's Church with its famous staircase towers majestically over Schwäbisch Hall's marketplace. It was consecrated on 10th February 1156 by the Bishop of Würzburg. From this period only the four bottom storeys of the Romanesque west tower have survived, along with the porch. From here the Archangel Michael – a stone sculpture from the late 13th century – watches over the trading on the marketplace and over the town as the guardian of justice. Outstanding works of Late Gothic art in the church interior include the large Netherlandish Passion Altar in the choir (c. 1460) and the Holy Sepulchre with its impressive mourners (1455/56).
From the marketplace the 53 steps of the vast staircase lead up to the Romanesque vestibule of the church, and another 160 steps take you up through the tower to the bell chambers and the former tower watchman's dwelling, which affords a magnificent view over the historic town centre. The staircase was constructed between 1507 and 1510/1511.
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.
