Geneva’s St. Pierre Cathedral is not just a place of religious importance, but historical importance as well. Commissioned in the 12th century, this cathedral is renowned for being the place that John Calvin, one of the heads of the Protestant Reformation who founded the concept of Calvinism, used to preach. In fact, you will even see the triangular stool utilized by the man himself inside. The building tells a story in itself. What started off as a Romanesque church was then crafted into a more Gothic architectural style, and after renovations centuries later, given a Neo-Classical exterior. During the tumultuous Reformation period, much of the interior was also sadly destroyed, but you can still see the pulpit and a few paintings intact. If you are up for some amazing views of the city, head to the top of one of the two towers, and enjoy panoramic views, seeing attractions such as the Jet d’Eau from above. A religious icon steeped in history, the St. Pierre Cathedral cannot be missed.
