Rapperswil Castle was built in the early 13th century AD by the House of Rapperswil. It is surrounded on three sides by the Lake Zürich and by those upper section on the northwestern Seedamm area. Thus, the castle was well protected, dominating the old town of Rapperswil, and controlling the water way between Walensee and Lake Zürich on its most narrow part, as well as the medieval Gotthard Pass route between Lombardy and Zürich.
Rapperswil Castle dates back around 1200 to 1220, and it was first mentioned in 1229 on occasion of the foundation of the Rüti Abbey. The castle was built by Count Rudolf II and his son Rudolf III von Rapperswil, when the nobility of Rapperswil moved from Altendorf (Alt-Rapperswil) across the lake. As before in the 11th and 12th century AD, the family acted as Vogt of the Einsiedeln Abbey. Sandstone from the Lützelauisland was used to build the castle, the town walls and the city.
The first chapel was associated to the castle, but the chapel was located outside of its walls and separated by a trench. The preceding building of the Liebfrauenkapelle was built as an ossuary around 1220 to 1253.
In 1350 an attempted coup by the aristocratic opposition (a central person was Count Johann II) in the city of Zürich was forcefully put down, and the town walls of Rapperswil and the castle were destroyed by Rudolf Brun. Eis-zwei-Geissebei, a Carnival festival hold in Rapperswil on Shrove Tuesday, may go back to the siege and destruction of the city of Rapperswil. The battlements and the castle were rebuilt by Albrecht II, Duke of Austria in 1352/54.
After the extinction of the line of Habsburg-Laufenburg in 1442, the castle was given to the citizens of Rapperswil. Ending Old Zürich War, Rapperswil was controlled by the Swiss Confederation from 1458 to 1798 as a so-called Gemeine Herrschaft, i.e. under control of two cantons of the Old Swiss Conferation and their representant, a Vogt, and Rapperswil castle became an administration site respectively military base and prison.
Over the course of time, the castle fell into disrepair. In 1870 the castle was leased for 99 years from the local authorities by a post-November 1830 Uprising Polish émigré, Count Wladyslaw Broel-Plater, who had been in Switzerland since 1844. At his own expense he restored the castle, and on 23 October 1870 the Polish National Museum was established.References:
Medvedgrad is a medieval fortified town located on the south slopes of Medvednica mountain, approximately halfway from the Croatian capital Zagreb to the mountain top Sljeme. For defensive purposes it was built on a hill, Mali Plazur, that is a spur of the main ridge of the mountain that overlooks the city. On a clear day the castle can be seen from far away, especially the high main tower. Below the main tower of the castle is Oltar Domovine (Altar of the homeland) which is dedicated to Croatian soldiers killed in the Croatian War of Independence.
In 1242, Mongols invaded Zagreb. The city was destroyed and burned to the ground. This prompted the building of Medvedgrad. Encouraged by Pope Innocent IV, Philip Türje, bishop of Zagreb, built the fortress between 1249 and 1254. It was later owned by bans of Slavonia. Notable Croatian and Hungarian poet and ban of Slavonia Janus Pannonius (Ivan Česmički) died in the Medvedgrad castle on March 27, 1472.
The last Medvedgrad owners and inhabitants was the Gregorijanec family, who gained possession of Medvedgrad in 1562. In 1574, the walls of Medvedgrad were reinforced, but after the 1590 Neulengbach earthquake, the fortress was heavily damaged and ultimately abandoned. It remained in ruins until the late 20th century, when it was partly restored and now offers a panoramic view of the city from an altitude of over 500 meters.
