The tense religious relationship in the 15th and 16th century resulted in practically no new Catholic churches being built.

In Prague the situation was similar. In Mala Strana (old part of Prague) the Lutherans and Calvinists had thair religious congregations. In 1584 one of them built a chapel which was called according to historical sources: chapel of Jan Hus or of St John the Baptist. Soon the chapel was too small. On July 20th 1611 the foundation was laid for a new Protestant church. It was after the attack on Prague by the mercenaries of Passau bishop and the abdication of Rudolf II. on July 26, 1613, that the church, which cost 62, 000 Rhenish guilders, was dedicated to the Holy Trinity. The interior of this Lutheran church was very simple. On May 23rd 1618 was the "Prague Defenestration", when the Czech Court Counsellor of Prague Castle was thrown out of the castle's windows by the Protestants of Prague. It was Vilem Slavata of Chlum and Koshumberk, and Jaroslav Borzita of Martinic who were the main opponent of their camp. With this the 30 year War was initiated. Currently Prague Cardinal Miloslav Vlk invited the Discalced Carmelites to return after 200 years to their church. That occurred on July 2nd, 1993. The purpose of their activity is, to reawaken the devotion to the Miraculous Infant Jesus and to give pastoral care to Czechs and pilgrims and visitors from all over the world.
