Nikola Subic Zrinski Square (famous Croatian "ban" - regional governor of imperial times) or more commonly known as Zrinjevac is a park in central Zagreb. It was the first park in Donji grad (Lower town or Downtown) and it brought a dash of modern times.
Parks in Zagreb
There are few cities in which parks and gardens are so inter meshed as in Zagreb. In the beginning of the second part of 19th century, when urbanistic planning focused on Donji grad (Lower Town or Downtown), an idea of series of parks bordering the new town centre was born. They are know as the Lenucci horseshoe because of the shape they form (letter "U") and the name of the landscape gardener who planned them. It is also common to call it "Green horseshoe" as the idea of series of parks was born long before Lenucci (but he contributed the most towards its realisation").
Urbanist trend of reserving enough space for parks, gardens or even whole avenues of trees and flowers still continues.
