The Constitution of Bulgaria designates Orthodox Christianity as the "traditional" religion of the country, but guarantees the free exercise of any religion.[6] Bulgaria has not experienced any significant ethnic or religious confrontation, unlike the case in former Yugoslavia in the 1990s. The religious communities in the country coexist peacefully. In fact, the capital Sofia is known for its so-called Square of Religious Tolerance; the St Nedelya Church, St Joseph Cathedral, Banya Bashi Mosque and Sofia Synagogue are located within metres of each other in the very centre of the city.
