Jabrin Castle, also known as Jabreen Castle, is an impressive fortification located in the heart of Oman, near the city of Nizwa. Built in the 17th century, this castle stands as a testament to the architectural ingenuity and the Omani Islamic art of its time. Specifically constructed in 1670 by Imam Sultan Bin Saif Al Y`arubi, it was a seat of Omani education and learning, housingschools for Islamic jurisprudence, medicine, and astrology. The castle features numerous rooms, high ceilings, beautifully painted wooden beams, and intricately carved doors, making it a marvel of design and decoration. Jabrin Castle was designed to be a palace and a beacon of knowledge as well as a defensive stronghold. Visitors can explore the various rooms and chambers, the castle's defenses, such as the secret escape routes, and enjoy breath-taking views from the battlements. The ornamental flourishes, such as the colorful wall and ceiling paintings, are particularly noteworthy, blending Islamic motifs with Persian influences. The castle has been well-preserved, allowing visitors to step back in time and appreciate the lavish lifestyle and the advanced educational standards of the time.
