Switzerland Zurich Mission

When was this opened?
January 26, 2013
On 18 September 1960, the Swiss-Austrian Mission was dissolved and the Swiss Mission (now the Switzerland Zurich Mission) and Austrian missions were formed. The founding of the Swiss Stake (now the Zurich Switzerland Stake), the first in Switzerland, came on 27 October 1961. Swiss Mission headquarters were moved from Basel to Zurich on 21 December 1962."
There's a comment feature there and a message one likewise. You could send the mission home that question and hear back directly. :)
Switzerland is a beautiful country. There was a time I aspired to live there as a graduate student in Bern, Geneva or Lausanne. Now if I get to visit before I die I'll be doing good. :)
