Hello, we are Clio Muse Tours, and we would like to welcome you on board. As you are about to begin your self-guided audio tour, we would like to introduce ourselves and our vision. We are a team of professionals, passionate about cultural heritage, and we aim to generate universal cultural awareness and guide you in every part of the world utilizing pioneering technology. It's high time we presented our author, Tommaso Raschiatore, a classical archaeologist, who is the ideal person to talk to you about Castel Sant'Angelo, given his passion for preserving and enhancing Rome's cultural heritage. Questioning whether it's a mausoleum or a fortress? Ready yourself to uncover the enthralling history behind this imposing structure. Discover the legend of an angel who miraculously brought an end to the plague that afflicted the city, and traverse a bridge that marries stunning beauty with a haunting past, since the bodies of those executed were once displayed there as a grim warning to others. Thank you for joining Clio Muse Tours, the leader in audio tours of archaeological sites and attractions, on this journey. Let us know your thoughts afterwards!
