H. A. N. W. E. everyone!

Monasterio de La Hoz, Hoces del Duraton. (Hoz = sickle, hoces = sickles, relating to the sharp meanders of the river Duraton)
Situated in the spectacular Hoces del Duraton, Segovia Province.
Built in the 13th century but flattened by the collapse of the rocky spur above it. I couldn't find any reference to loss of life so I presume (and hope) that the monks abandoned it at the first sign of danger!
