San Nicola is from Parma as well as … the Citadella.
It was founded as a fortress in the 16th century at the behest of Alessandro Farnese. As per the initial design, it still retains the pentagonal shape with bastions located at the vertices, all surrounded by a now dry moat. It has a main door open to the north decorated with a monumental facade in Angera stone and a smaller door facing south. Over time it has been used for various purposes: barracks, prison for political crimes and even as a place for executions. Now, after five centuries of existence, it is being used as a public park equipped with several spaces dedicated to sports and recreational activities for children.
