Brody Castle, Fortified castle in Brody, Ukraine.

Brody Castle is a ruined 17th-century bastion fortress built on a regular pentagon plan, with five bastions and curtain walls of earth faced with brick and stone. Inside the ramparts, casemates with cross vaults and hexagonal rooms with palm vaults on a central column served as barracks and stores. A deep moat, a drawbridge and a ravelin protected the gate, and in the mid-18th century a late-baroque Potocki palace and a clock tower were added at the northern curtain.

The fortress was built between 1630 and 1635 under the direction of Stanisław Koniecpolski, an influential Crown Hetman, with Italian architect Andrea del Aqua overseeing the work. It represented 17th century military innovations and served as a crucial defensive position for over 200 years.

The castle was not named after Koniecpolski; it took the name of the town of Brody, which replaced the earlier name Lubicze (Lubicz) in 1595. In 1755 the palace hosted the wedding of Teofila Potocka to Fryderyk Moszyński. A clock tower stood on the town side of the Potocki residence.

The citadel's gate faced the town, reached by a drawbridge and causeway, with a ravelin in front of the curtain wall. The bastions have simple shoulders, built like those of the Koniecpolski palace at Podhorce. From the town side, a clock tower was added in the mid-18th century.

The fortress contained roughly 75 casemented rooms that functioned as barracks and storage, allowing a permanent garrison to operate within its walls. These underground and semi-underground structures reveal how carefully military organization was planned in the 17th century.
