Most shops in Istanbul are open on Sundays. However, there are some exceptions:
- Large shopping malls: Typically open on Sundays, but may have reduced hours.
- Smaller independent stores: May choose to close on Sundays, especially in residential areas.
- Government offices and banks: Closed on Sundays, as well as public holidays.
- Museums and historical sites: Usually open on Sundays, but check individual websites for operating hours.
It's always a good idea to check the specific store's website or call ahead to confirm their opening hours, especially if you are planning a visit on a Sunday.
