Some of the top landmarks you will come across on Free Walking Tours in Geneva are the Jet d’Eau and St. Pierre Cathedral. The Jet d’Eau is a 140-meter-tall jet of water that shoots up at an incredible force at 200 km/hour. At any one time, 7 tons of water are plunged into the air. The St. Pierre Cathedral is Geneva’s Gothic-style cathedral. This magnificent building hosts free organ concerts during the summer. Additionally, wandering through Geneva’s Old Town, you will see the Reformation Wall and the Treille Promenade. Make sure you also check out the city’s chic commercial district and the popular flower clock, a tribute to local watchmakers. For those intrigued by international relations be sure to book a Geneva Free Walking Tour visiting the United Nations HQ, the Red Cross Headquarters, or the World Health Organization.
