Its fortifications have been replaced by boulevards beyond which extend numerous suburbs, while on the left bank of the Tarn is the suburb of
Villebourbon, which is connected to the town by a remarkable bridge of the early 14th century. This bridge is known as
Pont Vieux (i.e. "Old Bridge"). King
Philip the Fair of France officially launched the building of the bridge in 1303 while on a tour to
Toulouse. The project took 30 years to complete, and the bridge was inaugurated in 1335. The main architects were
Étienne de Ferrières and
Mathieu de Verdun. It is a pink brick structure over in length, but while its fortified towers have disappeared, it is otherwise in a good state of preservation. The bridge was designed to resist the violent floods of the
Tarn, and indeed it successfully withstood the two terrible millennial floods of 1441 and 1930. The bridge is a straight level bridge, which is quite unusual for Medieval Europe, where lack of technological skills meant that most bridges were of the humpback type. '' by
Antoine Bourdelle. The
Musée Ingres, on the site of the castle of the Counts of Toulouse and once the residence of the bishops of
Montauban, stands at the east end of the bridge. It belongs chiefly to the 17th century, but some portions are much older, notably an underground chamber known as the Hall of the
Black Prince (
Salle du Prince Noir). It comprises most of the work (including his "Jesus among the Teachers of the Law") of
Jean Ingres, the celebrated painter, whose birth in Montauban is commemorated by an elaborate monument. It is the largest museum of Ingres paintings in the world. The museum also contains some sculptures by famous sculptor
Antoine Bourdelle, another native of Montauban, as well as collections of antiquities (Greek vases) and 18th and 19th
ceramics. The
Place Nationale is a square of the 17th century, entered at each corner by gateways giving access to a large open space surrounded by pink brick houses supported by double rows of arcades. The is located in the palace built by the
intendant of Montauban (the equivalent of a
préfet before the
French Revolution), and is a large elegant 18th century mansion, built of pink bricks and white stone, with a steep roof of blue gray
slates, in a style combining northern and southern French styles of architecture. The chief churches of Montauban are
the cathedral, remarkable only for the possession of the "Vow of Louis XIII", one of the masterpieces of Ingres, and the church of St Jacques (14th and 15th centuries), dedicated to
Saint James of Compostela, the façade of which is surmounted by a handsome octagonal tower, the base of which is in
Romanesque style, while the upper levels, built later, are in
Gothic style. ==Economy==
