Nizwa Castle is the "King of a Thousand Castles" in Oman. It was built by Sultan bin Saif in the 17th century and took 12 years to build. It was once the core defense of the capital.
The circular main tower stands 24 meters tall, with walls 3 meters thick. It hides seven hidden doors and a boiling oil trap, along with an ingenious spiral staircase. The castle also houses a meeting hall, a date palm storehouse, and a mosque, now a museum showcasing Omani irrigation systems and crafts.
Suitable season for visiting: October to April of the following year.
The average daily temperature during this period is between 16-28℃. There is plenty of sunshine during the day but it is not scorching hot, so you won't feel the heat when walking inside and outside the castle. Especially in the winter from December to January, the temperature often drops to around 10℃ in the early morning. Climbing up the main tower of the castle, you can enjoy the beautiful picture of "oasis morning mist and castle silhouette", which is the golden time for photography.
Recommended places to visit:
1. Main Watchtower
As the heart of Nizwa Fort, the Main Tower is a must-see for visitors. Though its 10 spiral staircases are steep and narrow, each floor showcases a different military function: Floors 1-3 house the "Arsenal," displaying 17th- and 18th-century Arab scimitars, spears, shields, and arquebuses, some of which still bear the marks of their original use. Floors 4-6 serve as the "Observation and Firing Floors," with arrow slits and firing ports facing different directions. Visitors can peer through the holes to simulate the defenders' observation of the enemy and experience the tense atmosphere of ancient defense. Floors 7-10 house the "Command Floor," with a circular observation deck on the top floor offering unobstructed 360-degree views. To the north, one can gaze upon the vast outline of the Hajar Mountains, while to the south, one can overlook the whitewashed houses and dense date palm groves of the ancient city of Nizwa, interwoven like a silver network of oasis irrigation canals. The scenery is magnificent.
2. Circular Defense Corridor
Located between the main tower and the outer wall, the passageway is the castle's "attack and defense hub." Approximately 2 meters wide and 140 meters long, it's paved with smooth stone bricks, and the walls feature arrow slits or observation windows every 5 meters. The passageway's most notable features are the "trap door" and "underground chamber": the trap door, hidden beneath the stone bricks, could once have been opened by a mechanism, trapping attackers in a spike trap below. The entrance to the underground chamber, located midway, encompasses approximately 30 square meters and was once used to store food, weapons, and medicine. Cleverly designed ventilation holes in the walls kept the interior dry. Today, the chamber displays household items from the ancient defenders, such as pottery jars, oil lamps, and woven baskets, recreating the scene of "holding on to life" during wartime.
3. Weapons & History Museum
Located on the west side of the castle's ground floor, it's a crucial place to explore Oman's military history. The museum is divided into two exhibition areas: the "Military Equipment" exhibits a wide range of weapons from the 16th to the early 20th centuries, including Persian-style sabers, the traditional Omani "Khanjar" short sword (with a handle inlaid with ivory and gemstones), and models of large catapults used to defend against foreign enemies. The "History and Culture" exhibit, through graphic panels and physical models, recreates the construction of Nizwa Castle, the military expansion of the Yalubi dynasty, and the castle's offensive and defensive battles throughout history. The most striking example is the model of the "1692 Defense Against the Persian Army," which vividly depicts the fierce confrontation between the castle defenders and the attackers.
4. Outer Walls & Moat Ruins
Despite over 300 years of weathering, the castle's outer walls still retain their intact circular structure, with the battlements and battlements clearly visible. Visitors can stroll along the outer wall trails to closely observe the masonry craftsmanship—the seamless integration of basalt blocks and clay demonstrates the exquisite skills of ancient artisans. The moat surrounding the outer wall has dried up, replaced by a green belt of date palms and bougainvillea. Benches are provided along the trails for those tired of strolling, where they can sit and admire the fusion of the castle and the surrounding ancient city, experiencing the harmonious coexistence of "military architecture and everyday life."
5. Nizwa Souq (next to the castle)
Just 200 meters from the main entrance of the fort lies one of Oman's oldest and busiest souks, a stark contrast to the fort's military atmosphere. The souk is divided into the Spice Section, the Handicrafts Section, the Jewelry Section, and the Food Section. The Spice Section is filled with the rich aroma of frankincense, myrrh, and cardamom, where vendors grind spices on site and offer packaged spice souvenirs. The Handicrafts Section sells handwoven rugs, intricately carved date palm wood trays, and Arabic lamps inlaid with stained glass, each crafted by local artisans. The Naan and Honey Stalls in the Food Section are particularly popular. Freshly baked Arabic naan paired with fresh honey creates a delicious local flavor not to be missed.
