Predigerkirche ('Preacher's Church') is a monastic church to the Dominican friary adjacent to the church. Predigerkirche was originally built by the Dominican Order in the 13th century, when the mystic Meister Eckhart was prior here. The church only became a Protestant church after the Reformation. The original building was modified in 1340-50, and the bell tower was built between 1447 and 1488. Around 1806 Predigerkirche was used as a POW camp, which led to damage to the interior and the equipment. Repairs were made around 1826.
The first organ of Predigerkirche was installed in 1567, built by Heinrich Compenius der Ältere. His grandson Ludwig Compenius built a new, Baroque style organ by 1650; it was the largest and most expensive organ in the city. Today, Predigerkirche uses a Schuke organ built in 1978.
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.
