Religion and human history goes hand in hand. The right to religious worship is firmly anchored in our constitution. A secular state is definitely against disputes on religious grounds. Prague holds a key place in this process. Although there were some religious disputes in the past, Prague has always nurtured being a city amenable to new approaches, today even more so. Christians (Catholics, Protestants, Orthodox, Czech Brethren any many other), Jews, Muslims, Hindu, also Scientologists, supporters of New Age, traditional or modern religions, they all coexist in Prague side by side. What do people from the most atheistic capital of Europe know about these religions? What do they know about each other? That is what these pages are about.
