Although he was not successful in his attempt to recover Narbonne (737), he destroyed the fortresses of Agde, Beziers and Maguelonne, and set fire to the amphitheatre at Nimes.
Remains of an amphitheatre still exist.
It is situated on the Saale, near its junction with the Unstrut, in the centre of an amphitheatre of vine-clad hills, 29 m.
The ruins consist of an amphitheatre (now almost entirely demolished, but better preserved in the 18th century), a theatre, and a very fine aqueduct in opus reticulatum, the quoins of which are of various colours arranged in patterns to produce a decorative effect.
The Temple of Peace is a building of the Roman period of the 2nd century B.C., with six Doric columns on the front, eight on the sides and none at the back; it was excavated in 1836 and is now entirely covered up. Traces of a Roman theatre and amphitheatre (?) have also been found.
