The Nova Sich (Ukrainian: Нова Січ, lit. 'New Sich') or Pidpilnenska Sich (Підпільненська Січ, 'Underground / Сlandestine Sich') was the administrative and military center of the Zaporozhian Cossacks in 1734–1775, established after the return of the Zaporozhian Host's Lowland Army unto the Russian protectorate as a result of the signing of the Lubny Treaty. The last Zaporozhian Sich settled in the former lands of Davnia or Stara Sich (Ukrainian: Давня or Стара Січ, lit. 'Old Sich', hence the name Nova) and centered on a large peninsula, washed by the Pidpilna River (a tributary of the Dnieper).

Nova Sich was founded with the permission and under the supervision of the Russian government on March 31, 1734, by Ataman-Hetman I.Malashevich on the Right Bank of the Dnieper in the Great Meadow, which occupied 26 thousand acres.

The basis for the continued existence of the Nova Sich as a territory was signed in 1734, the Lubny Treaty [uk] on the recognition of the Russian protectorate by the Cossacks.

To oversee the actions of the Cossacks, the imperial government built a fortification 2 km from the Nova Sich with two half-bastions and a permanent garrison - the so-called Nova Sich retransmission.

According to historians, the Nova Sich retrenchment was erected in the Sich by the imperial government for the ostentatious purpose of helping the Cossacks in their war with the Ottomans, but in reality, for the hidden purpose of keeping them in their hands. However, the Cossacks well understood the reason for the construction of the Russian citadel, expressing their dissatisfaction with the words: "We have a Moscow sore liver." Given the historical events that took place during the existence of the Nova Sich, we must recognize that the imperial government achieved its goal by dissuading the Sich from participating in the nationwide struggle against deprivation.

On three sides, Sich was surrounded by Pidpilna, a tributary of the Dnieper River, which sailed Zaporozhian chaiky and Turkish and Greek merchant ships (tumbasy), which sailed to the Sich harbor in the river bay Ustup (Ukrainian: Уступ під Білою Косою). On the north-eastern side of the underground separated branch - the river Sysyna, flows into the Dnieper.

Sich was a city - a fortress surrounded by a rampart and palisades. The Pidpilnenska Sich consisted of three parts: the suburbs, or the so-called shop bazaar, where all tents and visitors had their shops and taverns for trade, where there were houses of market atamans and military canary or keeper of scales. This suburb was called Hassan-Basha. From it began the gate that led to the kish — the main fortification, where around the Sich Square were located 38 huts. The huts were spacious barracks. Between the huts of the Ustup Bay and the Pidpilna River is the Inner Kish or Palanka, separated by a wall from the Outer Kish. Palanka housed the houses of the Kish Otaman and Sich officers, as well as the Sich Cathedral Church of the Intercession of the Mother of God, the military chancellery, the treasury, and the houses of the clergy.
