You are interested in getting to know it while in Geneva, and I think it is a monument worth visiting. It does, in my view, paint a good picture of the impact of the reforms, particularly with the Protestant appearance of Calvin, born in Geneva, and his best mate, John Knox, and others. It is huge and grim, with no space to accommodate the gorgeous and environs of the Catholic Church and the huge walls themselves, depicting important dates in the history of the Reformation, relayed in a variety of different languages. Explained in English no more than in other languages. But do you really want a city and country with four official languages to invest more in English than in other languages?
