A peaceful spot along the Reuss River, perfect for a relaxing break. The old iron bridge adds a historic charm, and the calm waters beautifully reflect the sky. There’s a comfortable bench where you can sit and enjoy the view, and a gravel parking area nearby makes access easy. Ideal for a short stop during a walk or bike ride.

The place was first mentioned in documents in 1247 as "castrum", and in 1258 as "civis". In 1266 it appears as an "oppidum". Meienberg was founded by the Habsburgs and was provided with a tower and a ring wall. The town square measured around 200 metres, and had a sod well and a court linden tree. A green linden tree on a three-hilled hill is also the coat of arms of the town and office of Meienberg. Around 1300 the lords of Baldegg and Hünenberg owned the castle fief. Meienberg had neither a town ban nor a peace district, but it did have market rights and extensive grazing rights in the surrounding area. The office of Meienberg was first mentioned in 1273 and lasted until 1798. Meienberg's importance lay not in that of an urban community, but as a fixed point of power.
