The former Lectoure Cathedral dominates the town and the belfry tower of 1488 can be seen at a distance as the town is approached. The repairs and modifications of the cathedral go back to the 12th century. The unadorned west front erected in the 15th century has been modified through the ages, and niches above the door have all but melted away due to the fragility of the limestone.
The nave was vaulted at the end of the 12th century, then repaired in 1480. Vaulted chapels were added at the beginning of the 16th century and more alterations followed in the 17th and 18th centuries. The choir and apse were also reconstructed at the beginning of the 16th century, and the five square apsidal chapels were completed. The ambulatory was created in 1600 by introducing ten cylindrical piers, and the carved early 17th century choir stalls were placed here in the 19th century. The stained glass is typically 19th century with a Tree of Jesse in the Chapelle de la Sainte Famille.References:
The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
