Just in front of Vlaherna Monastery there is an island called Pontikonissi on which there is only one building: the church of Pantocrator. According to one interpretation of the Odyssey this island would be the ship of Ulysses that was turned into rock by Poseidon while, according to another legend would be the rock on which Ulysses' ship crashed during a storm.
The church of Pantocrator was built in the 13th century and to visit it you can take a boat from the small port opposite. The Byzantine chapel that is on the top of the island encloses the memorial tablets of Elizabeth Empress of Austria and Rodolfo archduke.
References:The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
