Aris ob Kien Castle

Aris ob Kien Castle is a medieval ruin in the municipality of Reichenbach im Kandertal, in the Swiss canton of Bern, close to Scharnachtal and the Kiental valley. A fragment of the tower survives together with ditches and earthen ramparts, the remains of a fortress that once watched a route towards the Valais.

What is Aris ob Kien?

The castle was the home of the Freiherren von Kien, a noble family, and the complex dates to the 12th and 13th centuries. Scholars regard it as the family's original seat. In the 13th century the Kien family left and settled at their second stronghold, Mülenen, nearby. Before 1290 their rights and lands passed to the Freiherren von Wädenswil. The surrounding territory later came under Bern, which acquired it in 1352 together with the lordship of Mülenen.

Why was it built here?

Aris ob Kien and Mülenen, the latter with a defensive barrier known as a Letzi, guarded the pack-animal route into the Valais. The Kander valley linked the Bernese Oberland with the south of the Alps, so two castles held by one family controlled the passage.

What can you see today?

This is a ruin rather than a castle with rooms to tour. The main features are:

• the remains of the tower, the clearest part of the layout,
• neck ditches cutting the hill off from the rest of the ridge,
• earthen ramparts still readable in the terrain.

The ruin was secured and restored in 1934. It is a quiet stop for castle and history enthusiasts, not a site with visitor facilities.

Where is it and how do you get there?

The site lies at roughly 46.609 N, 7.696 E, in the municipality of Reichenbach im Kandertal, where Kien-Aris and Scharnachtal are separate local communities (Bäuerten). Reichenbach is reached by train on the Lötschberg line side, and PostBus services continue into Kiental. Check a current hiking map such as swisstopo before you set out, since the ruin lies off the main valley trails.

What else is nearby?

The municipality stretches from the Niesen in the north to the Blümlisalp massif in the south. Kiental is a well-known base for walks: routes from Griesalp run about 9.5 km and take around 4.5 hours. Mülenen, the Kien family's second castle, is close, so both sites fit into one history-themed outing.
