St. Antönien is a Swiss village in the Prättigau and a former municipality in the political district of Prättigau/Davos in the canton of Graubünden.

[1] Earlier, the area was worked by romansh speaking inhabitants of the lower valleys as the names of the places indicate.

The Walser also brought with them the Valliser style of house, which uses more wood than stone St. Antönien has an area, as of 2006[update], of 52.2 km2 (20.2 sq mi) with settlements reaching as high as roughly 1800 meters at Gafia and Partnun.

Of the rest of the land, 0.9% is settled (buildings or roads) and the remainder (36.1%) is non-productive (rivers, glaciers or mountains).

[3] The village has been a minor tourism destination since 1891 when 30 to 40 guests stayed in homes that were empty due to the summer pasturing.

[4] Even though the first impression from the St. Antönien side would not seem to allow this, it is nevertheless possible to reach some of the summits on mountain paths without climbing.

The House with Barn at Berawis 68 is listed as a Swiss heritage site of national significance.
