Ringgenberg Castle Church from the 13th century Marvel at a medieval and baroque castle church The Ringgenberg Castle Church is a charming place, full of Bernese history and at the same time one of the most impressive castle complexes in the Bernese Oberland. It was built by Imperial Bailiff Cuno von Brienz in the 13th century. With the founding of the Swiss Castle Association in 1928, historical interest in the castle ruins arose. The Ringgenberg Castle Church stands proudly on the northern shore of Lake Brienz. Two monuments from different historical eras and areas of life can be found on the castle rock in Ringgenberg. Together, the ruins of the medieval castle of the high nobility and the Baroque reformed church form a contrasting, distinctive interplay. The courtly culture cultivated here in the Middle Ages can still be sensed. The ballroom in the tower is reminiscent of intoxicating parties with a view of the lake. Since 2008, the castle tower has been accessible via stairs, a gallery and a viewing terrace. Once at the top, you can enjoy a unique view over Lake Brienz. In contrast, there is the modesty of the hall church, which is geared to the needs of reformed services. In 1837, the castle church received its church organ, which Felix Mendelsohn played in 1847.
