The first fully documented use of the Grimsel Pass dates back to the 14th century, although it has been suggested that the pass was used in
Roman times and also, in 1211, by troops of
Berthold V, Duke of Zähringen. In 1397, the Landschaften of Pomat, Goms and Hasli, and the cities of
Interlaken,
Thun and
Bern, signed an agreement in which it was agreed to provide for free and secure trade by the
mule track over the Grimsel. In 1400, the hospice on the pass is mentioned for the first time. The Grimsel Pass formed, along with the
Nufenen and
Gries passes, a regional trade route between the
Haslital and
Domodossola and the
Lombardy plain.
Cheese and
cattle were sent south, whilst
wine,
rice,
corn and
olive oil came north. This trade continued until the opening of the
Gotthard railway in 1882. == Geography ==
