The Chios Maritime Museum is located in the center of the city, housed in a mansion belonging to the late Anastassios and Marouko Pateras. The house was donated in 1991 by the inheritors of the estate to a public benefit foundation, which bears their name. The structure has two floors. One of the essential goals of the Museum is to illustrate this significant social aspect of the island by collecting and classifying historical information of the maritime tradition of the area, as was the developments in shipping and in commercial ships. The museum also hosts a series of lectures and conferences on the subject of Chios and shipping in conjunction with other museums of the Greek Archipelago.
Exhibits such as sailboats, merchant ships, paintings, rare photographs, books, as well as segments of ships and other nautical objects depict the development of Greek naval force over the centuries. In the museum there are educational programs, events and conferences aiming at highlighting the history and traditions of the Greek merchant navy.
