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:
First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
