Below the Petrov Cathedral stretches the extensive “Denisovy sady” Park. It is a true oasis in the centre of the city. There are many benches scattered throughout the park, inviting you to sit down, and also a Music Pavilion with an adjoining colonnade. The park merges into the Capuchin Gardens.
It was open to the public in 1771, a Way of the Cross was built here with 14 small chapels and the hill was named Calvary. In the early 19th century, the slope beneath the castle walls was made into a park.
 
The park, then known as Františkov, was officially opened on 4th October 1818. Gradually, a botanical garden, Empire-style fountain (The Spring of Health), a wooden colonnade and a gazebo were added. In the mid-19th century, the colonnade was replaced by a Classicist building and the gazebo by a Neo-Renaissance music pavilion. In 1919, the Františkov park was renamed “Denisovy sady” after the French historian Ernst Denis.
 
By the 1990s, the park had fallen into a state of severe neglect and it was decided that it should be completely restored.  This was completed early in the 21st century.
