The Museum of Ethnography and Death Studies at Universitas Airlangga is one of Surabaya's more unusual small museums. Its collections look at cultural practices around death, ritual, burial, and memory, using ethnographic material rather than spectacle.
It will not suit everyone, but curious travellers may find it more memorable than another generic city museum. Visit with a respectful frame: the subject is sensitive, and the interest lies in how societies make meaning around mortality.
