Above, David Berlanda has written an excellent overview of this marvelous site. I went in Feb. 2008 by Swiss rail to Scoul where I stayed overnight at the excellent hostel next to the train station followed the next day by post bus to the Val Mustair. While I had only a few hours at St. John's Convent it remains one of my most treasured memories for the beautiful sweep and tranquility of the valley and the perfection, beauty and clarity of the frescoes in this intimate church. The religious architecture and art mesh in a pleasingly direct manner. There is a smaller chapel in front of the church where there may be more frescoes yet to be uncovered as I was told by a photographer working with an infrared camera.
I was told that the Benedictine hours have been continuously kept for over 1000 years first by monks, now by nuns and that the present order has invited younger sisters from the Philippines to join them. Some distance above the convent I've been told there is a lake possibly to hike to. I have Brother Antoine Galliker (deceased Jan. 2010)of the Abbaye de Fontaine-Andre in Neuchatel for encouraging me to visit The Convent of St. John at Mustair.
