In the Middle Ages, the island was home to a Cluniac priory, which was under the authority of the French mother monastery of Cluny. The Romanesque church and parts of the monastery, which are still visible today, bear witness to this period. The buildings were rebuilt and extended several times over the centuries, but always served as a spiritual and cultural centre of supra-regional importance.
A particularly well-known episode in the island's history took place in 1765, when the French-Swiss philosopher Jean-Jacques Rousseau spent several weeks on St. Peter's Island. In his writings, he describes the tranquillity and beauty of the place as one of the happiest times of his life – these impressions contributed significantly to the romantic image of the island.
Over time, the monastery lost its religious function. After the Reformation, the island became the property of Bern and served various purposes – from agriculture to storage and administration to tourism. As early as the 19th century, the potential of this unique location for guests from near and far was recognised. The historic buildings were gradually adapted for accommodation.
Today's Hotel St. Petersinsel was built in stages and combines historical charm with contemporary hospitality. The old monastery walls house stylishly restored rooms, a restaurant serving regional cuisine and event facilities that offer guests an unforgettable experience surrounded by nature.
Its special location, cultural past and proximity to nature make the Hotel St. Petersinsel a unique retreat steeped in history – a place that offers both tranquillity and inspiration.
