According to the historical records of Prague, in 1037, "After the funeral of his father Bretislav was led by hand to the Prince's throne by his uncle Jaromir. The custom during the election of the prince was the tossing of coins over the grills of the upper hall. Once the Prince was seated on the throne, there was a big lull, in the silence Jaromir holding his nephew's right hand said unto the people: 'Behold your Prince!'." (Comas, The Bohemian Chronicle) In 1060, Prince Spythnev II noticed on St. Wenceslas Day that St. Vitas church was not large enough to accommodate all the people who attended Holy Mass. St. Vitas had been built by St. Wenceslas himself in the shape of a Roman church, and St. Wenceslas was buried in the middle of the church. Standing nearby was a second church which was built over the grave of St. Adalbert. Prince Spytihnew II decided to tear down both churches and build one large church for both patron saints. The foundations for the new church were laid, walls were erected, but the building of the church was stopped after the Prince's death.

At the end of the 10th century the�Benedictine�Convent was founded at the Basilica of St. George. The female members of the Royal�family were raised and educated in this convent, many became Abbess who held the right to crown the�Bohemian Kings. During the middle ages many books of literary and artistic value were written in the convent's famous Scriptorium.

By the 11th century�Prague Castle was a massive fort with a perfected defense system, with churches, a Bishop's palace, and two monasteries.

During the first half of the 12th century the Castle was rebuilt into a real Medieval Castle with stone palaces, churches and houses. The Romanesque fortified stone wall with towers protected the castle for several centuries.
