Beautiful palace complex. There is a luxurious garden with gazebos, a pond and even waterfalls.
Yildiz was the last refuge of the sultan and his family in the 19th century, so the luxury of palace life was preserved here, unlike Dolmabahce, which found the time of the Revolution and the rule of Ataturk.
There are pavilions with small museums around the perimeter - a harem, a library, a greenhouse, in general, everything that made up the daily routine of the rulers.
In front of the palace there is a beautiful mosque in the Gothic style, which, by the way, is in operation.
A big advantage of visiting Yildiz is the opportunity to buy a ticket at the same time as the right to visit Dolmabahce.
The downside is that you can't take pictures anywhere, but if you're careful and unobtrusive, you can. In general, I recommend you to visit.
There is nothing to see here after the Topkapi and Dolmabahce palaces. There is, of course, a park with a pond with blooming water, but beyond the wall the park is much more beautiful and also free (There is a beautiful pond with large carp and picnic tables). Part of the way from Dolmabahce is steep, so keep in mind. It's not worth your money
Beautiful nature park. Very clean. Beautiful paths and pedestrian bridges. Fountains and waterfalls. There are toilets (payment by mastercard). There is a cafe.
