Are there skyscrapers in Sharjah?

There are, but there are significantly fewer of them than in Dubai (including DoubleTree by Hilton).
In general, the emirate treats its historical heritage very carefully. For example, in the center of Sharjah, all buildings have been carefully restored according to historical drawings. Here you can immerse yourself in the atmosphere of the ancient eastern city and visit several interesting museums: history, calligraphy, art, etc.), as well as explore the 19th century fortress and traditional markets.
