Location

Letzis usually consisted of:

  • hill castles on the valley sides or on heights either side of the valley
  • defensive walls, often in combination with other bastions, running transversely across the valley in order to seal it completely. Because these parts of the position were typically unable to use the advantage of height, they had some of the character of lowland castles.

Because they had a combination of elements of hill and lowland castles, letzis did not fall neatly into either category.

The walls were often several kilometres long, for example in Rothenthurm SZ, and were often combined with ditches.

Such defensive valley barriers were still being built in the 19th century, for example the Forte della Chiusa and Buco di Vela.
