Forts and Castles of Oman

Oman is known for its hundreds of forts, castles and watchtowers — round mountain towers, mud-brick oasis castles and the harbour forts of Muscat. The map shows the best-known ones, most of them restored and open to visitors.

Overview

Why Oman has so many forts

For centuries power in Oman was divided between the imams of the interior, coastal rulers and outside powers — the Portuguese held Muscat and other ports in the 16th–17th centuries until the Ya'ruba imams drove them out. Oases, wadi mouths, passes and harbours were all fortified. Many forts were in poor condition by the mid-20th century; since the 1970s and especially from the 1980s the Ministry of Heritage has restored dozens of them as monuments and museums.

Bahla Fort — UNESCO World Heritage

Bahla Fort, with the surrounding oasis and its long mud-brick wall, was inscribed on the UNESCO World Heritage List in 1987. It dates mostly from the 13th–14th centuries, when Bahla was the base of the Banu Nabhan. It is the only Omani fort with World Heritage status in its own right.

The Ya'ruba forts: Nizwa, Jabrin, Rustaq, Al Hazm

The 17th and early 18th centuries produced the most famous buildings: Nizwa Fort's great round tower (built in the 1650s under Imam Sultan bin Saif), the palace-fort of Jabrin (1670s, painted ceilings), the expanded fort at Rustaq — the first Ya'ruba capital — and Al Hazm Castle (completed 1711).

Opening hours and tickets

Restored forts are typically open daily except for reduced hours on Friday, and charge a small entry fee (Nizwa Fort costs more than most). Hours and fees change and differ between forts, so check locally. Al Jalali and Al Mirani in Muscat are not generally open to the public.

Practical tips

Wear sturdy shoes — stairs are steep, narrow and uneven, and roofs have low parapets.
Photography is generally allowed; flying a drone needs permission from the Civil Aviation Authority.
Combine Nizwa, Bahla and Jabrin in one day from Nizwa; Nakhal, Rustaq and Al Hazm in one day from Muscat or Sohar.

Locations

Al Hazm Castle (Forts & Castles, Al Batinah South). Castle completed in 1711 by Imam Sultan bin Saif II, unusual for its massive stone-and-mortar construction without timber beams. The imam's tomb is inside.

Al Jalali Fort (Forts & Castles, Muscat). Portuguese-built (1580s) fort on the rocks guarding the east side of Muscat harbour. Not generally open to the public; best seen from the waterfront by Al Alam Palace.

Al Mirani Fort (Forts & Castles, Muscat). Fort on the west side of Muscat harbour, facing Al Jalali; rebuilt by the Portuguese in the 1580s. Not open to the public, but part of every Old Muscat harbour view.

Bahla Fort (Forts & Castles, Ad Dakhiliyah). UNESCO World Heritage fort (inscribed 1987), built largely in the 13th–14th centuries when Bahla was the base of the Banu Nabhan. Mud-brick walls; the oasis is ringed by a long defensive wall of roughly 12 km.

Jabrin Castle (Forts & Castles, Ad Dakhiliyah). Palace-fort completed in the 1670s by Imam Bil'arub bin Sultan as a residence and seat of learning. Famous for its painted ceilings, carved wooden doors and the imam's tomb.

Khasab Castle (Forts & Castles, Musandam). Castle on the Khasab waterfront built by the Portuguese in the early 17th century, restored as a museum of Musandam life, boats and traditional houses.

Nakhal Fort (Forts & Castles, Al Batinah South). Fort built on a rocky outcrop above Nakhal oasis on the Batinah side of the Hajar, with earlier foundations; the Ain Al Thowarah hot spring is a short drive up the wadi.

Nizwa Fort (Forts & Castles, Ad Dakhiliyah). Built in the 1650s by Imam Sultan bin Saif al-Ya'rubi. Its great round tower (about 36 m across and 30 m high) dominates the oasis, and it is one of the most visited monuments in Oman.

Rustaq Fort (Forts & Castles, Al Batinah South). One of the largest forts in Oman, with four towers, built over earlier foundations and much rebuilt. Rustaq was the first capital of the Ya'ruba imams in the 17th century.

Sohar Fort (Forts & Castles, Al Batinah North). Whitewashed fort near the Sohar waterfront, restored with a museum on the city's history as a medieval trading port.

Sunaysilah Fort (Sur) (Forts & Castles, Ash Sharqiyah South). Square fort with four corner towers on a rise above Sur, built to guard the town and the approach from the interior.
