Trinil is a small riverside locality in Ngawi Regency, East Java, but its name carries an outsized place in the history of human palaeontology. In 1891 and 1892, Dutch physician and anatomist Eugène Dubois found hominin fossils in deposits beside the Bengawan Solo, then called the Solo River. The skullcap and other remains became central to debates about human evolution and the early classification of Homo erectus.
The visitor destination today is the Trinil Museum, in Pilang hamlet, Kawu village, Kedunggalar District. Indonesia’s Ministry of Culture places it about 15 kilometres from Ngawi town in the direction of Solo. The museum was opened on 20 November 1991 to mark the centenary of Dubois’s Trinil discovery. It is a local institution as well as a stop in the history of science: the site’s meaning depends on both the fossils and the generations of research that reconsidered them.
