The Ibi Mosque is located in Bozcaada Square, opposite the park, which is believed to have been built in 1700. It is also likely that it was built in place of the Ali Agha Mosque, which dates back to the sixteenth century, which Miralai Ahmed Agha destroyed and renovated. The courtyard of the mosque is entered through a circular arched door, where you see some inscriptions dating back to 1903, and this mosque is also characterized by being built of red stone, in addition to decorating the interior with picturesque ornaments, inspired by the Baroque era.
