The carillon  encourages us to pray every hour when we visit the Loreto. At the time it was put into operation - at the end of the 17th century - it was a true rarity in Bohemia.

It was given to the Loreto by the rich merchant from the Lesser Town, Eberhard von Glauchau. The author of all thirty signed bells (only one was damaged in the 18th  century and replaced) was the Amsterdam town bell-founder Claudy Fremy, who made them between 1683-91. The consecration of the bells in the Loreto in 1695 before they were set in the clock-tower was a grand occasion. Every bell had its sponsor from among the ranks of the high aristocracy; Emperor Leopold I assumed patronage of the first of them.
Over the next few months the Prague clockmaker Peter Neumann arranged the carillon and attached it to the clock mechanism of the tower in the facade; he created a mechanism on the principle of a metal cylinder with pegs for setting various melodies (‘pantomúsos’). At the same time, the carillon can be controlled by means of a two-and-a-half octave keyboard on which various compositions are played up to the present day on church holidays. The Prague carillon is a very complex mechanism, similar to the carillon in Amsterdam, Delft, Brugge and Berlin. The tuning of the bells is relatively pure and thus the carillon can be used as a distinctive musical instrument. On 28th September 1695 the Loreto bells rang over the Prague roofs for the first time.
    The Prague Loreto Carillon is unique especially for its authenticity – it is one of the last surviving Baroque musical instruments in Europe the mechanism of which was not modernised in any way. You will certainly find the sound of music heard in Loreto itself is a remarkably different experience than listening to it while standing on the square – the carillon was designed to be listened by the Loreto pilgrims gathered in the courtyard beside the Santa Casa.
