amazing place to see in istanbul! would recommend if you are interested in cool sights, history and unique experiences. although depending on what time you go you might have to wait in a long queue so definitely check that.

This is the largest of several hundred ancient cisterns that lie beneath the city of Istanbul. I went to this place last year.

When I went to Turkey to play the World Championships in August, I went to the hotel I stayed in 🏨, next to the Hagia Sophia ⛪️. Because it is one of the most famous attractions in Istanbul, the queues here are very long every day. There is also a green channel on the spot, which is a fast channel for online booking 🎫. There are also staff 👩‍💼 next to it to teach tourists how to buy tickets. Considering the inconvenience of operation, We still chose to queue normally. Tickets are 350 lira. I think there are previous strategies that say 10 lira and 20 lira. I don't know if it's here or the price has increased in recent years. As the walking stairs go down, I see this mysterious underground palace. The water palace has a half-football field large, high interior, rows of towering columns supporting the entire building, with arches at the top, adding to the artistic feel of the water palace. The water is not deep, the water is built to watch the lights, the lights change from time to time, so that the whole water palace is full of mystery, can also feel the grandeur of the whole building shock. With the twists and turns of the viewing trail, there are many landscapes worth checking in. It takes about 15~20 minutes to visit the entire water palace. Relatively speaking, the price of the groundwater palace is not cheap. The Russian, Japanese and Korean chess players who are in the same group have given up visiting. I think this is also a landmark attraction in Turkey. If you can accept the fare of about 120 yuan, it is recommended to visit.

In the era of reinforced concrete, such a underground pool was built. The dome structure of the mosque actually played a big role.

It is worth it, the price is a bit too expensive! The price is not high! Buy tickets on Trip.com to force!

it is amazing inside! well organised, the staff were kind and attentive. There is a students discount.you have explanations of everything inside.
