During the Thirty Years' War, Prague was besieged by a Swedish force, and a part of the city fell into the hands of the invaders. The history of the city is largely a chronicle of combats, for it was constantly assailed by armies and disturbed within. Protestantism received its deathblow in Prague, in 1621, after the great battle of the White Mountain. The Austrian War of Succession was scarcely at an end before the outbreak of the Seven Years' War of Frederick the Great, when the famous "Battle of Prague" was fought. We now enter upon a more tranquil period of Bohemian history. Writing of the architects of Prague, in "Cities," Mr Arthur Symons asserts that "there is something in their way of building, fierce, violent, unrestrained, like the savagery of their fighting, of their fighting songs, of their fighting music." One of the most interesting of the sacred buildings is the Gothic Cathedral of St Vitus, designed by Petrlik. The decoration is still unfinished, but the edifice has beautiful slender spires, and an ornate tower. The chapels of the Cathedral contain several memorials of note, but there are no paintings of great artistic value. Several sovereigns and their consorts are buried here. The Tyn Church has a very fine front. Within is the grave of Tycho Brahe. A church of a later period is St Nicholas. The Strahov Monastery has been reconstructed repeatedly since the days when it was founded in the twelfth century. A "Madonna" by Albrecht Durer is one of the treasures of the monastery. There is a very richly painted and carved ceiling in the library. The Capuchin Monastery, and the Emaus Monastery, are both of historic importance, and the Church of St George is one of the handsomest in the city. Palaces abound in Prague, and one of the most characteristic is that of Count Clam-Gallas, with a noble gateway, decorated with statuary. On the Hradcany is the Castle, which was the residence of many of Bohemia's kings and queens. It is approached by two fine courts and an ancient doorway; the older part of the building dating from the period of Vladislav, whose magnificent hall is of great architectural interest. There are several more old palaces in Prague, such as the Kinsky and the Morzin, which all invite a lengthy inspection. All the bridges spanning the river are beautifully planned. One of the finest is the Karl Bridge, dating from the fourteenth century, and adorned by many images of saints and heroes. The Powder Gate (Prãsna Brana) was erected by Vladislav II. and served as a storehouse for ammunition. It is a strangely ornamented structure, with carved escutcheons, many effigies, and flamboyant decorations on each of its sides. The gate or tower is surmounted by a wedge-like steeple. The Bohemian Museum is a modern building, finely adorned with statuary. It contains a large collection of arms and armour, coins, books, and manuscripts of interest.
