St Christine of Lena is an Asturian pre-Romanesque church located in the Lena municipality, on an old Roman road that joined the lands of the plateau with Asturias.
The church has a different ground plan to Pre-Romanesque's traditional basilica. It is a single rectangular space with a barrel vault, with four adjoining structures located in the centre of each facade. The first of these annexes is the typical Asturian Pre-Romanesque vestibule, with a royal tribune on the upper part, accessed via a stairway joined to one of the walls. To the east is the enclosure with the altar, with a single apse, foregoing the traditional Asturian pre-romanesque triple apse, and going back to Visigoth influences. To the north and south respectively, there are two other enclosures through semicircular arches and barrel vaults, whose use was associated with the Hispano-Visigothic liturgy practised in Spain up to the 11th century.
One of the most particular elements of Santa Cristina de Lena is the existence of the presbytery elevated above floor level in the last section of the central nave, separated from the area intended for the congregation by three arches on marble columns. This separation, which appears in other Asturian churches, is not repeated in any other with a similar structure. Both the lattices over the arches and the wall enclosing the central arch were re-used from Visigothic origins in the 7th 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.
