Tuor la Praschun (Prison Tower), Susch

Highlight • Historical Site

Tuor la Praschun / Prison, Sush
The tower, made of quarry stone, dates from the 12th or 13th century. It has a square floor plan with a wall length of 7.5 meters. The wall thickness is 1.3 meters on the ground floor and tapers to around 1 meter on the two upper floors. Narrow notches and square windows are still visible on the facades. The large windows on the east and north sides are more recent, as is the current entrance on the south side.
The high entrance was on the first floor on the south side; Bar holes indicate a pedestal in front of it. The low tent roof was covered with wooden shingles until the 1930s, since then with Eternit plates. The tower probably originally had low battlements.
A paneled dance hall with a dais and a platform for the musicians was installed on the second floor in the 18th century.
As the chronicler Nicolin Sererhard reported, prison cells were built into the tower in the post-medieval period on the ground floor, later it served as an ammunition store and from 1849 as a fire station.

The potentially fatal dangers are pointed out at the gate: falling rocks and danger of falling. Unimpressed by this, a robot lawn mower is meticulously doing its job in the courtyard. And as it works, the restorers have done their job: stone chips and the risk of falling are eliminated. Only my search for the "Lustgarten" was strangely unsuccessful.

Kapfenstein Castle Ruins

Highlight • Castle

Beautiful, small castle ruins with a view of the valley. The valley walls are still intact, though those facing the gorge were demolished long ago.

A truly epic, large ruin with a heavy gate, which is open, however! Only the tower is inaccessible!

This refers to the Fortezza Rohan near Susch. An impressive building in a dominant position on a hill near Susch.

Remains of the fortress built in 1675 during the Grisons Wars on a hill above Susch. Impressive ruins with a beautiful panoramic view of the central Engadin. The two hiking trails up the hill are rather steep, and often require pushing the bike.

Opposite there is a white tower on the hill. It is made of marble and is empty inside. The acoustics are a sensory experience, as are the small sculptures in the garden. A visit to the museum is worth it. The facility was bought back by the original owners in 2009 and high-quality exhibitions take place in the public area.
