Panagia Gremniotissa is perhaps one of the most picturesque churches on Ios Island, and is a fabulous place to watch the sunset in Ios. The church stands on the highest point of the main village of Chora, and has a white bell tower with a blue dome roof. A tall palm tree stands in the courtyard next to the church.
The church was built in 1797, and a festival is held here on the 15th of August each year.
Panagia Gremniotissa church is one of the most photographed sights in Ios Greece.
