The Nizwa Fort is a mix of a castle, a fort and a museum. Reflecting the old Omani architecture, the Nizwa Fort is unique due to the circular shape of tower which can be climbed. The Fort was built at the beginning of the 17th century which took approximately 12 years to complete. The Castle was originally built in the 9th century and renewed in 1624, which originally was made up of rooms decorated and used to display artefacts, kitchen, and coffee-making room. A visit to the Nizwa Fort transports visitors to the ancient era.
