The Assumption of Christ or Panagia Thalassitra, is the patron saint of sailors and the most photographed church on the island. It is located in one of the most beautiful parts of the island and you will meet it as you go up to the Castle. This church in 1739 was a nave that was demolished to build in its place in 1839 this beautiful larger church, integrating as a southern aisle and the adjacent Frankish church of Panagia Eleousa.
In Panagia Thalassitra you can see works of the 17th century from the famous hagiographic workshop of Skordilida, and specifically the important icons of Agios Eleftherios and Panagia and Christ, creations of Emmanuel Skordilis. Also, you can see the wood-carved iconostasis with a very nice cross, while in the infrared of the west door of the church you can see the coat of arms of the Duke of Naxos, Crispi.
