The Charles Bridge, a Gothic bridge connecting Old Town and New Town is a popular tourist hotspot. Charles IV, the Holy Roman Emperor built the bridge in 1357 as a trade route and over the centuries it was beautified with an alley of Baroque statues of saints. Though the replicas have replaced the original, tourists still love walking across the bridge to visit the various kiosks, vendors and admire painters painting masterpieces of the bridge.
Prague is dotted with various medieval churches that are open to the public free of charge. This includes the Church of Our Lady Before Tyn where famous Danish astronomer Tycho Brahe is buried. The highlight of the church is its impressive 20-story high tower, rising above the neighbouring houses.
St. Vitus Cathedral, the country's most important and biggest church is the seat of the Archbishop of Prague. Located within the Prague Castle complex, the visually overwhelming cathedral contains the tombs of many Bohemian kings and Holy Roman Emperors. Entrance is charged, but a part of the structure can be visited for free. One can hear the ring of all seven cathedral's bells every Sunday afternoon.
