St. Michael's Church in Fulda is considered to be the oldest Holy Sepulchre church in Germany, built in the Carolingian architectural style (Pre-Romanesque) by the abbot Eigil in the years 820-822. It served as a burial chapel to Fulda monastery founded in 744, which was one of the prominent cultural centres of the early Middle Ages. St. Michael stands in the neighbourhood of Fulda cathedral, and the architect was probably the monk Racholf (d. 824).
The rotunda and crypt remain preserved from this time. In the 10th and 11th century, the church was extended from the rotunda, and a west tower was built. In 1618 the roof over the rotunda was rebuilt with a conical roof, and in 1715-1716 a chapel was added to the north side. Wall paintings in the interior date from the 11th century.
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.
