Eternal Spirit of the chainless Mind! <br /> Brightest in dungeons, Liberty! thou art, <br /> For there thy habitation is the heart— <br />The heart which love of Thee alone can bind. <br />And when thy sons to fetters are consign'd, <br /> To fetters, and the damp vault's dayless gloom, <br /> Their country conquers with their martyrdom, <br />And Freedom's fame finds wings on every wind. <br />Chillon! thy prison is a holy place <br /> And thy sad floor an altar, for 'twas trod, <br />Until his very steps have left a trace <br /> Worn as if thy cold pavement were a sod, <br />By Bonnivard! May none those marks efface! <br /> For they appeal from tyranny to God.<br /><br />George Gordon Byron<br /><br />http://www.poemhunter.com/poem/on-the-castle-of-chillon/
