Gate to Shah Abbasi Caravanserai.
The ancient caravanserai is a rectangular building with a walled exterior and a courtyard open to the sky. It had a single door, wide enough to permit large animals like camels to gain access together with people.
The caravanserai in Meybod has been restored and made into the nice carpet museum and a modern Shahabbasi Caravansary Restaurant.
Today people don't travel on camels to it any more :)
