Is it possible to visit historical monuments on public holidays like Arbaeen?
It depends on the holiday. For example, on Arbaeen all the tourist areas and historical monuments are closed. You can just enjoy hiking or you can go on a picnic. But on some other holidays, you have no restrictions and can do any activities. It is better to check the holidays with your travel agent and tailor-made your itinerary in a way you can do the most.
