Turkey has one of the richest castle landscapes in the world — over 3,000 fortifications spanning Roman, Byzantine, Seljuk, Crusader, Armenian, Karamanid and Ottoman military construction, layered across a country where every mountain pass, Bosphorus narrows and Mediterranean harbour was worth defending for 2,000 years. Anadolu Hisarı on the Asian Bosphorus shore is the oldest Turkish monument in Istanbul — built in 1394 and partially derelict in its upper sections. Ani's fortress complex on the Armenian border contained the walls of an entire abandoned medieval capital. And Zilkale in Rize province rises from a 1,130-metre cliff above the Black Sea valleys in a state of dramatic decay.

Why Turkey Is One of the Best Countries for Abandoned Castle Exploration
The sheer number of distinct military powers that have controlled Turkish territory — Roman, Byzantine, Arab, Armenian, Seljuk, Crusader, Mongol, Karamanid, Ottoman — means that almost every strategic point in the landscape carries successive layers of castle construction. Many were simply superseded rather than destroyed, left in progressive dereliction when their strategic purpose was replaced by the next invader's newer fortification on the same hill.
1. Ani Fortress Complex – Kars Province, Armenian Border — Medieval Armenian Capital Walls, 9 Civilisations, Cathedral 989 AD, Abandoned for Centuries, UNESCO 2016 (Known Location)
Ani's fortress system is among the finest examples of medieval military architecture in the Middle East — the walls, gates and towers of a city that held 100,000 people at its 11th-century peak under the Bagratid Armenian kingdom, before Mongol invasion, earthquakes and centuries of neglect reduced it to the extraordinary ruin field visible today on the Kars plateau. The Cathedral of Ani (989–1010 AD) remains standing to full height despite centuries of abandonment; the Church of the Redeemer retains half its structure; and the curtain walls with their round towers follow the dramatic Arpaçay River gorge on the Armenian border. Listed as a UNESCO World Heritage Site in 2016. Accessible from Kars, approximately 45km; small admission fee.
2. Anadolu Hisarı (Anatolian Fortress) – Bosphorus, Asian Shore, Istanbul — Built 1394 by Bayezid I, Oldest Turkish Monument in Istanbul, Derelict Upper Sections, Bosphorus Narrows Setting (Known Location)
Anadolu Hisarı — built in 1394 at the narrowest point of the Bosphorus as Sultan Bayezid I's preparation for the siege of Constantinople — is the oldest surviving Turkish monument in Istanbul. After its military purpose ended following the 1453 Ottoman conquest, it served briefly as a prison before gradual neglect. A TripAdvisor reviewer describes it well: "there is more than enough left of this castle to give you an accurate idea of what it was like before it was abandoned — its strategic importance at the mouth of the Bosphorus is obvious. The view of the Black Sea is spectacular." The lower sections have been partially restored; the upper tower ruins remain in evocative decay on the Bosphorus cliff.

3. Zilkale Castle – Çamlıhemşin, Rize Province — Built at 1,130 Metres Above Sea Level, Black Sea Mountain Setting, Medieval Fortress, Progressively Ruined, Remote Access
Zilkale Castle rises from a cliff at 1,130 metres in the Fırtına Valley above Çamlıhemşin in Rize Province — one of the most dramatically sited mediaeval fortifications in Turkey, overlooking a deep gorge cut through the Pontic Mountains above the Black Sea. Istanbul Property identifies Zilkale as among the most visually spectacular castles in Turkey. The specific combination of the Black Sea's extreme green-and-mist mountain landscape, the vertiginous cliff setting and the castle's advanced state of structural decay creates a ruin experience of unusual atmospheric intensity. Reachable by road from Çamlıhemşin; the final section requires a short uphill walk. GPS in our Turkey Urbex Map.
4. Mamure Castle – Anamur, Mediterranean Coast — Roman 3rd–4th Century, Seljuk & Karamanid Reconstruction, 23,500 m², One of Turkey's Best-Preserved Medieval Castles, Sea-Edge Location (Exclusively on Our Map)
Mamure Castle, 6km south of Anamur on the Mediterranean coast, is one of Turkey's largest and most complete medieval fortifications — 23,500 square metres of Roman, Byzantine, Seljuk and Karamanid military construction built directly on the Mediterranean shoreline. Istanbul Property confirms it as "one of Turkey's most prominent and safest castles." The castle's extraordinary completeness (towers, curtain walls and internal structures largely intact), its direct Mediterranean sea-edge location and its relative obscurity outside Turkey make it one of the most rewarding castle visits in the country.

5. Uçhisar Rock Castle – Cappadocia — 60-Metre Volcanic Tuff Formation, Byzantine Fortress, Underground Passages Mostly Blocked, Highest Point in Cappadocia (Off the Radar — Our Map Only)
Uçhisar, situated on the edge of Göreme National Park, is dominated by a 60-metre-high castle-mountain which is visible over a wide distance and has the form of a large cylindrical tower. This massif is crisscrossed by numerous underground passageways and rooms, which are now mostly blocked or impassable — they served as residential areas, as well as cloisters in Byzantine times. Originally, around 1,000 people lived in the castle, but it is no longer inhabited today. The mostly-blocked underground passages — beyond the managed tourist areas of the castle exterior — represent a specifically Cappadocian castle experience: Byzantine military engineering in soft volcanic tuff, largely inaccessible. Find them on our Turkey Urbex Map.
Safety Tips
- Ani border zone: sections of the site near the Armenian border are restricted — follow all signage and never approach the border fence
- Zilkale mountain access: the Fırtına Valley road can be impassable after rain; the castle approach path is steep — proper footwear and current weather check required
- Unstable masonry: derelict tower sections at all sites carry collapse risk — never stand beneath overhanging stonework
- Never explore alone — particularly at remote sites like Zilkale and Ani where mobile coverage is unreliable
❓ FAQ
What is the most impressive derelict castle in Turkey?
Ani on the Armenian border — the fortress walls, cathedral and churches of a medieval city that held 100,000 people, abandoned for centuries and now a UNESCO World Heritage Site. For sheer cliff-edge drama, Zilkale in Rize province at 1,130 metres above the Black Sea gorge is remarkable. For accessibility from a major city, Anadolu Hisarı on the Istanbul Bosphorus — the oldest Turkish monument in the city — is within easy reach of central Istanbul.
How many castles does Turkey have?
Over 3,000 fortifications have been catalogued across Turkey — an extraordinary density reflecting the successive military cultures that have controlled Turkish territory for 3,000 years. From Roman coastal forts to Byzantine highland refuges, Seljuk caravanserai-fortresses, Crusader strongholds on the Mediterranean coast and Ottoman Bosphorus control points, almost every landscape feature in Turkey carries some form of military heritage.
Can I visit Ani without a guide?
Yes — Ani is accessible independently from Kars (45km, taxi or car required). The site has a managed entrance with a small admission fee and good information panels in Turkish and English. A local guide significantly enhances the historical depth of the visit and is recommended but not required. Always follow the site signage; sections near the Armenian border are restricted.
