  building_fortress_andorra_01_desc:0 "The monasteries of Andorra have become reinforced over the years by numerous defenses on all sides. The Andorran fortress-monasteries have earned the reputation of being the most well defended temples in the whole world, for they protect within their bowels centuries upon centuries of books, possessing the greatest of the Church's archives second only to the Vatican itself. Should Andorra fall, countless years of knowledge - both pre- and post-Event - will be lost."
