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 Amphitheatre of the Three Gauls was part of the federal sanctuary of the three Gauls dedicated to the cult of Rome and Augustus celebrated by the 60 Gallic tribes when they gathered at Lugdunum (Lyon). The amphitheatre was built at the foot of the La Croix-Rousse hill at what was then the confluence of the Rhône and Saône.
Excavations have revealed a basement of three elliptical walls linked by cross-walls and a channel surrounding the oval central arena. The arena was slightly sloped, with the building"s south part supported by a now-vanished vault. The arena"s dimensions are 67,6m by 42m. This phase of the amphitheatre housed games which accompanied the imperial cult, with its low capacity (1,800 seats) being enough for delegations from the 60 Gallic tribes.
The amphitheatre was expanded at the start of the 2nd century. Two galleries were added around the old amphitheatre, raising its width from 25 metres to 105 metres and its capacity to about 20,000 seats. In so doing it made it a building open to the whole population of Lugdunum and its environs.
