The date of the foundation of Prague by Libussa is as uncertain as everything concerning that semi-mythical princess. Hajek of Libocan, a chronicler of the sixteenth century, gives the year 752 as the date of the foundation of the castle on the Hradcany Hill. It was at first of a very simple character, consisting probably but of wooden buildings. During the reign of Libussa's successors--of whom little but their names is known[3]--we have scant information as regards the growth of Prague. After the introduction of Christianity one of the earliest Christian churches is stated to have been erected on the Hradcany at Prague. The new settlement rapidly extended itself, and from an early date we read of the 'suburbium Pragense,' which extended on both banks of the river and included the present Malá Strana (small quarter) at the foot of the Hradcany Hill, as well as that part of the Staré Mesto that is nearest to the Vltava. Though there is but little trustworthy information concerning this early period, it is certain that the city gradually spread out on both banks of the river. They were from the earliest historical period united by a bridge that stood near the site of the present far-famed bridge. Buildings not connected with either the Vysehrad or the Hradcany settlements sprang up at a very early period. According to Professor Tomek, as early as the year 993 some houses stood on the site of the present Poric Street (close to the State Railway Station). Immediately after the introduction of Christianity, but particularly during the reign of the pious Wenceslas (920-935), many churches were erected at Prague, though the earliest building devoted to Christian worship was at Levy Hradec.[4] According to some accounts a church on the Hradcany was dedicated to the Virgin by Borivoj, the first Christian ruler of Bohemia. It was in this church that St. Wenceslas received the tonsure. The earliest church on the Vysehrad probably dates from nearly the same time. Prince Wenceslas--afterwards sainted--built several churches, and also laid the foundations of the first buildings on the spot where St. Vitus's Cathedral now stands. Wenceslas was induced to build this church by the gift of an arm of St. Vitus, a precious relic that he received from the German King, Henry I. The first church of St. Vitus, like all the earliest religious buildings in Bohemia, was in the Romanesque style. In 939 the remains of St. Wenceslas were conveyed here from Stará Boleslav, where he had (in 935) been murdered by his treacherous younger brother, Boleslav.[5]
