Building Rebuilt by Duke Albert II, since 1354 the castle forms an almost equilateral triangle, and each corner of the castle is reinforced with a tower. The highest tower in the southwest is the
donjon, commonly called
Gügeliturm in Swiss-German language, where the so-called
Hochwächter warned the residents against approaching danger or fire. The five-sided
Zeitturm, a clock tower in the east, houses three bells and beside a sundial and two large clocks. Between these two towers the castle's six-storey palais is situated. In addition, ramparts respectively
battlements are leading to the third tower in the northwest, the so-called
Pulverturm (powder tower). From 1698 to 1837 there was a drawbridge, at the present lower gate towards the former
castle chapel. The French revolutionary troops plundered the castle's interior in 1798. Rapperswil - Altstadt - Gründungslegende IMG 3079 ShiftN.jpg|Legend of founding on a house at

Interior Inside the castle's palais, there is located next to the Polish Museum the
Schloss Restaurant. After-hours visits are available by appointment, as well as guided tours for groups, though the castle is only partly accessible for the public. The impressive
Rittersaal (knights' hall) and the historical wooden architecture, as well as some pictures and tapestries, include further points of interest. Schloss Rapperswil - Innenansicht Palas 2011-08-06 14-50-48 ShiftN2.jpg|

St. John's church in the background The city and local board of Rapperswil-Jona initiated in 2011 a new service and operating concept for the Rapperswil castle to provide the site as a touristic attraction and meeting place, and thus
recognizable as a brand. For this purpose, the tower, the battlements and the herb garden were opened to the public.
Lindenhof hill In 981 AD the assumably oldest
vineyard on Lake Zurich lake shore, situated on the southern slope of the Lindenhof hill which is named
Schlossberg was mentioned for the first time. On the castle's terrace, the eastern part of the so-called
Lindenhof hill-square, the Polish freedom pillar is situated, as a sign of Switzerland's solidarity with people who struggle for their freedom, as well a tiny
rose garden. From there is also an impressing view over the medieval town of Rapperswil,
upper and lower
Lake Zurich, on the
Seedamm and the
wooden bridge from Rapperswil to
Hurden and the
Frauenwinkel protected area, and towards the
Glarus Alps, as well as to the
Bachtel mountain. Among other traditions,
Eis-zwei-Geissebei is celebrated on Lindenhof, at the
Rathaus and Castle when in the evening all regional
Guggenmusik (carnival marching bands) gather to celebrate a roaring concert. On the northern side of the
Lindenhof plateau stretches a supervised Deer park with 10 to 15
Dama dama down towards the
Kempratnerbucht which is a reminder of the legend of the castle's founding. == State of research ==
