Together with the cloister and the mortuary, the two-aisled Eichstätt cathedral is regarded as one of the most important medieval monuments in Bavaria. The first Roman Catholic cathedral of Our Lady and Sts. Willibald and Salvator was built in the 8th century. It was destroyed during the Hungarian invasions but the church preserved. Parts of this church have been preserved in the masonry.
The current cathedral has parts built between the 11th century and the 16th century. Bishop Heribert (1022-1042) started the construction in Carolingian-Ottonian style and bishop Gundekar II inaugurated the cathedral in 1060.
The Gothic west choir dates from 1250-1270. The east choir was reconstructed in the late 14th century. The Roritzerkapelle (1463-1480) and cloister (1410) where added later.
The west façade was restored in Baroque style in 1716-1718 and the pulpit was made in 1720. The rococo altar dates from 1745.
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.
