The Pont Neuf is a 16th-century bridge in Toulouse across the Garonne river. Original planning for the bridge started in 1542 by the assembly of a committee of master masons and carpenters. Construction started on the foundations in 1544; the first arch was started in 1614. The bridge was finished in 1632, and was inaugurated on 19 October 1659.
The bridge is not symmetrical; the longest arch is the third from the right-hand bank. The openings through the piers were originally supposed to represent the face and mane of a lion. A triumphal archway added in 1686 constricted traffic and was removed in 1860.References:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
