Inside the bell tower in the middle of impressive Loreto facade the great musical gem is hidden. Baroque carillon encourages us to pray every hour during the Loreto visit. At the time of it's creation - 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 twenty seven signed playing bells (only one was damaged in the 18th century and replaced) was the Amsterdam town bell-founder Claude 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.
