St. Peter's Bridge ( or , in older sources also à  ent Peterski most or à  entpeterski most), also Ambroà ¾ Bridge (), is a bridge in Ljubljana, the capital of Slovenia, that crosses the river Ljubljanica in the northeastern end of the old town. It is a continuation of Rozman Street (). West of it lie Vraz Square () on the northern (left) bank of the river and Ambroà ¾ Square () on its southern (right) bank. East of it lies the Petkovà ¡ek Embankment () on the northern bank and the Poljane Embankment () on the southern bank. The bridge is named after the nearby St. Peter's Church. It is intended primarily for motorised traffic, but is also used by pedestrians.
Originally, a wooden footbridge held over the Ljubljanica on the site. It was property of Bishops of Ljubljana, who used it to access their land on the other bank. According to a legend, unconfirmed by historical sources, Bishop Thomas Chrön (1560âÂÂ1630) led a procession of the Blessed Sacrament across the footbridge, guarded from the Lutherans by the blacksmiths of Ljubljana. The story tells that the Chrön Cross at nearby Grain Square (), now Ambroà ¾ Square, was erected in remembrance of their victory.
In 1776, the wooden Bridge Behind the Barracks () replaced the footbridge. It was built to link St. Peter's Barracks north of the river and the Poljane residential district south of it. In 1835, it was replaced by a new one. There were actually two bridges, the wider one used by draft animals and the narrower one by pedestrians, and from the beginning of the 20th century, by the Ljubljana tram.
The construction of the present iron and concrete bridge started at the beginning of the 20th century. Due to World War I, it was only completed in 1918. The wooden bridge was transferred to the Prule neighbourhood, where it then served as the Prule Bridge.
