The Basilica of St. Stephen in the Round on the Celian Hill (Basilica di Santo Stefano al Monte Celio), commonly named Santo Stefano Rotondo, is Hungary's 'national church' in Rome. It is dedicated to both Saint Stephen, the Christian first martyr, and Stephen I, the sanctified first king of Hungary who imposed Christianity on his subjects.
The earliest church was consecrated by Pope Simplicius between 468 and 483. It was dedicated to the protomartyr Saint Stephen, whose body had been discovered a few decades before in the Holy Land, and brought to Rome. The church was the first in Rome to have a circular plan, inspired by the Church of the Holy Sepulchre in Jerusalem.
The church was embellished by Pope John I and Pope Felix IV in the 6th century with mosaics and colored marble. The church was restored in 1139-1143 by Pope Innocent II, who abandoned the outer ambulatory, and three of the four side chapels. He also had three transversal arches added to support the dome, enclosed the columns of the central ambulatory with brick to form the new outer wall, and walled up 14 of the windows in the drum.
In the Middle Ages, Santo Stefano Rotondo was in the charge of the Canons of San Giovanni in Laterano, but as time went on it fell into disrepair. In 1454, Pope Nicholas V entrusted the ruined church to the Pauline Fathers, the only Catholic Order founded by Hungarians.
The altar was made by the Florentine artist Bernardo Rossellino in the 15th century. The painting in the apse shows Christ between two martyrs. An ancient chair of Pope Gregory the Great from around 580 AD is preserved here.
The Chapel of Ss. Primo e Feliciano has very interesting and rare mosaics from the 7th century.
The Hungarian chapel is dedicated to King Stephen I of Hungary, Szent István, the canonized first king of the Magyars. The frescoes of the chapel were painted in 1776 but older paintings were recently discovered under them.
Under the church there is a 2nd-century mithraeum, related to the presence of the barracks of Roman soldiers in the neighbourhood. The cult of Mithras was especially popular among soldiers. A coloured marble bas-relief from the 3rd century is today in the Museo Nazionale Romano.
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.
