Explore Catania's UNESCO-listed old town on a self-guided walking tour that doubles as a treasure hunt. Your mission: find the lost treasure of Saint Agatha, the patron saint credited with saving Catania from Etna's eruptions time after time, before a secret society gets to it first. You will start at Porta Garibaldi, the striking black-and-white lava gate, and the trail takes you past the city's greatest sights: Castello Ursino and its legends, the Benedictine Monastery (one of the largest in Europe), the church of San Nicolo l'Arena (the biggest in Sicily), the ancient Roman Odeon and the Terme della Rotonda. At each stop you will investigate your surroundings (inscriptions, statues, facades and hidden details) to solve a puzzle that reveals your next clue, plus real historical facts and local legends about the places you're standing in. You can play alone or bring your whole group, any day and any hour: just book a ticket and start whenever you want. The walk takes about 90-120 minutes with optional coffee breaks, and it ends right on Piazza del Duomo, by the Cathedral of Saint Agatha and the Amenano fountain, in the very heart of the city.
