Beautiful playground with fireplace, located in a small forest.

Grottenstein is a cave castle of undetermined age at the foot of a rockface on Calanda mountain. A 20-metre-long section of wall remains to this day of the castle built under a rocky bluff.

 Haldenstein gets its name from the castle above the village. Haldenstein Castle was build in the mid-12th century and was the seat of the house Haldenstein. The castle was inhabited until the end of the 17th century, before it was destroyed by earthquakes in 1769 and 1787.

The sparse ruins of Wackenau castle lie about 3 kilometres north-west of the village on a promontory above the Rhine. The ruin lies within 20 minutes walking distance from a car park west of Bonaduz. Just above the caste hill you can get a great view of Ruinaulta canyon from the panorama platform named after the castle. 

The St. Luzi chapel is situated at an altitude of about 900 metres, about 45 minutes on foot from the old town of Chur on a hiking trail in the direction of Mittenberg. It is located within a rock grotto and forms a picturesque but also wild place of peace and reflection. It is under the patronage of Luzius of Chur and is owned by the St. Luzi Seminary of the Chur Theological University.

Hikers can climb up to Mittenberg, to the village of Maladers or further up to Fürhörnli or even Montalin. Experienced bikers appreciate the technical descent from the Mittenberg via St. Luzikapelle into the valley.

St. Martin's Church was originally a Romanesque church built in the 8th century and conse-crated in 769 AD. It was named after St. Martin, Bishop of Tours. The church was largely destroyed during the great fire of 1464. It was rebuilt in late Gothic style and reused parts of its Carolingian predecessor. Construction was completed in 1491 and it is the largest late-Gothic building in Graubünden. This church in the Old Town was a centre and base for the Reformation in Chur from 1523. Since 1919, the three glass windows by artist Augusto Giacometti have been a special feature of this church. They depict the Christmas story.

The new pedestrian connection in Chur not only bridges the difference in height between the Plessur and Halde school grounds, but turns it into an eventful path with a rapid succession of views of the cathedral, the old town, the mountains, and the Plessur and Rhine Valleys.
Although the connection leads under a road, it runs above ground as much as possible, closely following the slope of the topography and thus giving you the feeling of being «in the countryside». Most of the structure touches the rock, is carved out of the rock, or lies snug against the rock. The roof over this massive base is made of weather-proof steel.
