“ Avila ‘of the Knights’ was, before all else, a fortress. When the walls were built, churches and suburbs were left outside the enclosure, that the military advantages of the height on which the old town stands might not be lost. These walls of dark-red granite girdle Avila to-day, unbroken, formidable, intact. They rise so high that they shut out from view all that they enclose, except the towers of the cathedral. Near San Vicente the masonry is fourteen feet thick, and forty-two feet in height. ”
