Step onto the ancient frontier of the Roman Empire on this daily Zerzevan Castle tour from Diyarbakir, a full-day private excursion to one of South-East Anatolia's most remarkable archaeological sites. Rising above the plains near Çınar, Zerzevan Castle (Samachi) was a strategic Roman border garrison that commanded the whole valley and guarded a vital stretch of the ancient trade route. With a private vehicle and an English-speaking guide, this day trip pairs the windswept ramparts of the fortress with the mysterious Mithras Underground Temple, a rare sanctuary of the soldiers' sun-god cult that once spread across the Roman world.
After breakfast you set out from Diyarbakir toward the hilltop fortress of Zerzevan Castle. Occupied for centuries, this Roman garrison kept watch over a huge area thanks to its commanding position above the valley and the caravan road below. Today you can walk among its walls, watchtowers, church, administrative buildings and rock-cut shelters, picturing the legionaries who once held this remote edge of empire.
The highlight for many visitors is the underground Temple of Mithras. Mithras — a god of Persian origin associated with light, war, justice and sworn friendship — was worshipped as a sun deity whose cult became hugely popular among Roman soldiers in the 2nd and 3rd centuries AD, fading only as Christianity spread in the 4th century. Initiates, who were exclusively men, advanced through seven secret stages, and ceremonies were held in hidden caves and underground temples like this one. Descending into the rock-cut sanctuary is a genuinely atmospheric way to connect with the ancient world before returning to your hotel in Diyarbakir.

Zerzevan Castle Day Tour Programme After breakfast your private tour sets out from Diyarbakir toward Zerzevan Castle (Samachi) near Çınar. Strategically placed above the valley on the ancient trade route, this Roman border garrison once kept a vast area under control, and with your English-speaking guide you explore its walls, towers, church and other remains while taking in the sweeping views. You then descend into the Mithras Underground Temple. Mithras, a god of Persian origin, was the sun-god associated with the ideas of agreement and friendship, and also with light, war, justice and faith. His cult became very common throughout the Roman Empire in the 2nd and 3rd centuries AD and lost its importance as Christianity spread in the 4th century. The Mithras religion was especially widespread among soldiers; those who joined — only men were accepted — passed through seven stages, and the secretive ceremonies took place in caves and underground temples. After exploring the site you return to your hotel in Diyarbakir.

My husband and I chose Inca Tour for our honeymoon and we are so glad we did. The boutique hotel selection was beautiful and the Bosphorus dinner cruise was so romantic. Thank you for making our trip special!
It was important for us to have a guide who spoke Russian, and Ender was wonderful. He explained every detail at Dolmabahce Palace. The Princes Islands day trip was a beautiful break from the busy city.
Our guide Ender was incredibly knowledgeable about Turkish history. The hot-air balloon ride at sunrise in Cappadocia was the highlight of our trip. Everything was perfectly organized — from airport pick-up to the last d...
Ender was our Italian-speaking guide and we felt like family. He took us to local spots tourists never see. The hotel choice in Sultanahmet was perfect for walking everywhere.
10+ years later we still talk about our Cappadocia balloon ride and the Bosphorus sunset cruise. Some memories are timeless. Thank you Inca Tour!
