The Balangay Shrine Museum is Butuan's most important cultural site, housing the excavated remains of ancient plank-built boats that were discovered at this site in the 1970s. The balangay boats — nine have been found so far — are the oldest watercraft discovered in Southeast Asia and prove that Butuan was a significant centre of long-distance maritime trade long before Spanish colonisation.
The museum is built around the excavation site itself, with the boats preserved in situ. Some are in surprisingly good condition, showing the sophisticated joinery technique (the planks were fitted together with wooden dowels rather than nails) that allowed these vessels to sail across the open ocean. The museum is about 5 km from the city centre and requires a short ride. It is free to enter and guides are usually available.
