If only the mighty walls of An Naman Castle could talk! But seeing they can't, inquire if tours are available to hear a couple of its fascinating tales instead.
You'll be spoiled for sightseeing choice when spending time in Barka. An Naman Castle is a great place to begin here, but there are lots of other fine places to consider. Barka Souq, and Barka Fort are close to the fortified complex and will top off your day nicely.
