The Triple Bridge is a group of three bridges across the Ljubljanica River. It connects the Ljubljana's historical, medieval, town on one bank, and the modern city of Ljubljana, capital of Slovenia, on the other.
The central bridge is partly built from Glinica limestone. Other parts are built from concrete. The balustrades with 642 balusters are made of artificial concrete. The platform is covered with granite blocks laid in 2010. Previously, it was covered with asphalt.
There is mention of a wooden bridge in this location from 1280. It was at first called the Old Bridge and later the Lower Bridge, in contrast to the Upper Bridge that was built in the location of the nowadays Cobblers' Bridge in the same century. It was also named the Špital Bridge after the nearby poorhouse, which was established in the early 14th century. It was built anew in 1657 after a fire.
In 1842, the Lower Bridge was replaced by a new bridge designed by Giovanni Picco, an Italian architect from Villach, and named Franz's Bridge, in honor of Archduke Franz Karl of Austria. It also became known as the Franciscan Bridge. This bridge, opened on 25 September 1842, had two arches and a metal fence.
In order to prevent the 1842 stone arch bridge from being a bottleneck, the architect Jože Plečnik designed in 1929 the extension of the bridge with two footbridges at a sligh angle on each side of it. In collaboration with his student Ciril Tavčar, who drew the plans, he published the proposal in the same year in the journal Ljubljanski Zvon. Construction started in 1931 and continued until spring 1932. The bridge was opened for traffic in April 1932.
The bridge was renovated in 1992. Since 2007, all the three bridges have been part of the Ljubljana pedestrian-only zone.References:
Ängsö Castle was first named as "Engsev" in a royal charter by king Canute I of Sweden (r. 1167-1196), in which he stated that he had inherited the property after his father Eric IX of Sweden. Until 1272, it was owned by the Riseberga Abbey, and then taken over by Gregers Birgersson.
From 1475 until 1710, it was owned by the Sparre family. The current castle was built as a fortress by riksråd Bengt Fadersson Sparre in the 1480s. In 1522, Ängsö Castle was taken after a siege by king Gustav Vasa, since its owner, Fadersson's son Knut Bengtsson, sided with Christian II of Denmark. However, in 1538 it was given by the king to Bengtsson's daughter Hillevi Knutsdotter, who was married to Arvid Trolle.
In 1710, the castle was taken over by Carl Piper and Christina Piper. Ängsö Castle was owned by the Piper family from 1710 until 1971, and is now owned by the Westmanna foundation. The castle building itself was made into a museum in 1959 and was made a listed building in 1965. It is currently opened to visitors during the summers.
The castle is a cubical building in four stores made by stone and bricks. The lower parts is preserved from the middle ages. It was redecorated and expanded in the 1630s. The 4th storey as well as the roof is from the expansion of Carl Hårleman from 1740-41. It gained its current appearance in the 1740s.
