The Bridge of Prado (Ponte do Prado) over the Cávado River was originally a Roman bridge. It was re-constructed during the 16th century when the original had been destroyed following flooding and consistent use. There are few vestiges of the Roman bridge.
The bridge's exit (to the north) fronts the Praça do Conselheiro Sousa Lima, a gardened area, the site of a 16th-century pillory marking Prado's historical importance as a municipality until the 19th century.
The flat-top shallow cantilever bridge consists of nine Roman arches that progressively increase in size the closer to the centre of the span, with the three largest arches slightly peaked. Eight triangular abutments protect the base of the bridge from debris, while polygonal structures downstream act as reinforcements.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
