Montesiepi Hermitage-Siena-Tuscany - A plate next to the sword informs: "In 1180 on top of Montesiepi Hill, Galgano Guidotti drives his sword in this stone, worshipping it as the Cross symbol of peace and redmption." I totally ignored the existence of that.
That's me sketching the sword.
In the same area there is San Galgano Abbey. Good information about the whole are here http://www.sangalgano.info/index_en.html
