Bastion of Doroshenko, Bastion in Chyhyryn, Ukraine.

The Bastion of Doroshenko is a 17th-century fortification on Bohdanova Hill in Chyhyryn, rebuilt in 2007. Built on the old Italian fortification system, its embrasures offer a view over almost the entire town.

The bastion formed part of the fortress complex on Bohdanova Hill and was the main stronghold during the siege of Chyhyryn in 1677–1678. Built on the old Italian fortification system, it withstood attack: 15,000 Cossacks held it against a 220,000-strong Turkish army. The defence was commanded by Patrick Gordon, a Scottish officer in the Russian army. Its ruins were excavated in 1989–1990 and the monument was reconstructed in 2007.

The bastion carries the name of Hetman Petro Doroshenko, whose influence shaped this region. What visitors see today reflects the military power of the Cossacks and their rule over this territory.

The site is open year-round, allowing visitors to view the reconstructed structure from various angles. It is best visited in clear weather so the details of the walls and fortifications are easy to see.

In 2017 a 17th-century burial containing 200 skulls was found in Chyhyryn; researchers suggest they were the heads of the bastion's defenders. The ruins themselves were only located in 1989–1990, when local scholars dug on Bohdanova Hill together with a team from the Institute of Archaeology of the National Academy of Sciences of Ukraine.
