My one day to see Istanbul is October 4, Eid-Ul-Adha.
Due to the religious holiday I am not sure what museums and mosques will be open.
For example, I think Topkapi Palace and Dolmabahçe Palace are closed.
Could someone direct me to a web site that shows what is open on October 4 so I can create a comprehensive itenerary based on what is open?
Thanks very much
