It was the first bastion-style castle constructed in the lands of the Grand Duchy of Lithuania.
The castle foundations were laid in 1564 by Mikołaj 'The Black' Radziwiłł.
The defensive system included deep moats and earthen ramparts that were once filled with water from local streams.
During the 17th and 18th centuries, the castle hosted significant diplomatic receptions and royal visits.
Following World War II, the site was repurposed as a psychiatric hospital, which occupied the premises for decades until restoration efforts began in the early 21st century.
Olyka Castle is a 16th-century fortification in the Volyn region, built by the Radziwiłł family as their primary residence. It serves as one of the best-preserved examples of a palazzo in fortezza, blending defensive walls with palatial architecture. The complex features a square courtyard enclosed by four two-story residential wings and distinct corner bastions. Historically, it functioned as the political and social hub for the Radziwiłł dynasty for over 300 years. The site is currently a branch of the Volyn Regional Museum, which oversees ongoing preservation and restoration efforts. It is notable for its transition from a high-security military fortress to a lavish noble residence over the centuries.
