The Krasiński Garden, originally designed in the Baroque style, was established in 1676 as part of the larger Krasiński Palace and garden complex. Spanning an initial area of 3.4 hectares, it held the title of Warsaw's largest park until the establishment of the Saski Garden. In 1765, the garden was acquired by the State to serve as the headquarters for the Crown Treasury Commission, and the following year, in 1766, it was opened to the public.
A significant event took place on the evening of November 29, 1830, when the November insurgents engaged in a victorious battle against the Volhynia Regiment on the western border of the garden. This triumph allowed them to seize control of the nearby Arsenal, along with all the weaponry stored within it.
During World War II, the park area fell outside the boundaries of the Jewish ghetto. Unfortunately, both the park and the Krasiński Palace suffered considerable damage during the Warsaw Rising, as they became a site of fierce fighting. It was in this garden that the Chrobry I Battalion, among other insurgent groups, fought valiantly.
Following the war, the park area was expanded to 11.8 hectares by incorporating neighboring grounds that had not been reconstructed after the war damage. Among the park's ancient trees, which date back to the late 19th century, you can find remarkable specimens such as ginkgo biloba, eastern black walnut, Turkish hazel, and Caucasian wingnut. During the early years of the 21st century, the park became a nesting site for 27-29 bird species during the summer, with a similar number of species wintering there. This was largely due to the abundance of old trees and clusters of shrubs. Notable features of the park's garden architecture include a pond with an artificial cascade, a flowerbed aligned with the Palace, and a modern playground. In 2013-2014, an archaeological field survey was carried out in the northern part of the park in an attempt to locate the Bund archive, but unfortunately, the endeavor was unsuccessful.
In the park's western section, facing the former Nalewki Street, stands a Baroque gate that has been partially preserved, along with a fragment of the original fencing. Towards the eastern edge, you will find the Krasiński Palace, which is currently owned by the National Library, as well as the Supreme Court complex, built between 1996 and 1999. Moving towards the west of the park, you'll come across the Royal Arsenal building, home to the State Archaeological Museum, and the monument dedicated to the Heroes of the Battle of Monte Cassino, which was unveiled in 1999. Additionally, the site where Simons' Passage existed before the war now features a monument honoring the Warsaw Insurgents, revealed in 1989.
