During formation of the Alps, layers of sediment were deposited by ancient bodies of water. This gave rise to the banded rocks that form the Lindenhof hill in Rapperswil, and the islands of Ufnau, Lützelau and Heilighüsli. During the last Ice Age the island was under a thick layer of ice. Over time, only the harder layers of conglomerate rock and sandstone remained after the erosion by the glacier, creating the islands.[1]
According to an inscription, the present stone building dates back to 1551. The chapel became the site of an execution after a legal dispute over a pasture belonging to the Wydenchlösterli, a nunnery on the shore of the Jona River. The Wydenchlösterli was a small Beguine nunnery founded by the House of Rapperswil. In the years before the Reformation in Zürich, its last superior, Katharine Scheuchzer (Katharina Schüchter) fought that the nunnery should be dissolved, and asked the neighboring Rüti Abbey and the Old Swiss Confederacy for support. When an epidemic in the Rapperswil hospital broke out in 1563, Scheuchzer was accused of witchcraft.[2] Although the Tagsatzung's verdict of 1543 was in favor of the small nunnery, after cruel torture, the old woman was sentenced by the town council to death, put in a bag, and drowned in the Obersee lake at Heilig Hüsli chapel. The property of the nunnery was transferred to the hospital.[3]
After the Seedamm was built in 1878, the Heilig Hüsli chapel was the only remaining structure of the original medieval wooden bridge. It stood isolated in the lake and was not accessible to visitors until the reconstruction of the former wooden bridge was completed in 2001.
Architecture
The chapel stands on an approximately 4 metres (13 ft) high base, and measures just 2 metres (7 ft) x 3 metres (10 ft), with eaves standing at about 3.5 metres (11 ft). It has a west-facing apse, in which a miraculous fresco was once installed. The altarpiece, whose outlines are still visible in the interior, is preserved together with a representation of the Virgin Mary with the body of Christ in the Stadtmuseum Rapperswil-Jona. The fresco was replaced by a replica by the Swiss artist Marlies Pekarek, and was inaugurated and blessed on 7 April 2011 with the intention of returning the bridge chapel to its original purpose.[4] The interior of the chapel is visible only through the latticed east side. Following an old custom, pilgrims throw coins into the interior.

As of today the small chapel is owned by the Ortsgemeinde (citizenry's community) Rapperswil. The chapel was partially renovated in 1908, 1930, 1957, 2011 and 2015.
