The UAE has a huge number of forts with many of them being really beautiful. They also have a whole lot of history behind them.
Here’s a nice website which has compiled nearly all (or perhaps all) of the forts here. Each fort has a page of its own, which mentions its history and also has some lovely pictures.

Who knew that “Do-buy” had so much history?
