The Commandery of the Order of the Hospital of St. John of Jerusalem is located in the municipality of Hohenrain. It is one of the oldest Hospitaller settlements in Switzerland. It was first mentioned in 1182/83 as a commandery. Parts of the complex, dating from the late 12th and 13th centuries, have been largely preserved as part of a medieval castle belonging to the Order. According to the inventory of cultural property, it is considered a cultural asset of national importance. Today it belongs to the Canton of Lucerne. Source: Wikipedia; see also Wikipedia: History

I missed the castle ruins last time, this time I discovered them just through the treetops. I researched at home and it might be worth looking at more closely.

Heidegg Castle and its surroundings are highly recommended. Heidegg Castle is a museum and is open from April to the end of October, Tuesday to Friday from 1:30 p.m. to 5:00 p.m. On weekends, it is open from 10:00 a.m. to 5:00 p.m. Admission for adults is CHF 13. I haven't been to the museum myself, but since admission is free with the Raiffeisen card, I'll definitely visit sometime. The castle has a rose garden. It is open from 8:00 a.m. to 8:00 p.m. starting in May. Admission is CHF 2 for adults and CHF 0.50 for children (cash or Twint). The entrance fee goes towards the maintenance of the garden. It's a truly beautiful place with seating and a view of Lake Baldegg. I saw lizards, bumblebees, and butterflies there, and of course, admired the various flowers. There is an outdoor playground in the chestnut avenue near the castle. This serves as a popular meeting place year-round. The snack bar is open on Sundays and public holidays from April to the beginning of October, weather permitting, from 11:00 a.m. to 5:00 p.m. For information about whether the snack bar is actually open and all other information, please visit the website www.heidegg.ch.

A wonderful area on the ascent to Horben. In good weather, you can enjoy perfect views of the Alps.

Even in the rain the lock makes a good trap.

Heidegg Castle may not be the largest of all castles in Switzerland. But it is well preserved and open to the general public. The park offers a fantastic view and inside, a well thought-out museum with interactive elements awaits its visitors. A small shop for young and old offers all sorts of things. As always, climbing the stairs is a must in historic buildings! But if you don't have the strength, you'll really enjoy the wooden tower stairs. We were absolutely thrilled during our visit. But if you're expecting the early Middle Ages, you'll unfortunately be a little disappointed.

Unfortunately, I only realized where I should have looked when I got home, but it's not the end of the world yet.
