If you’ve finished visiting all the sites in my Virtual Southeast Asian Archaeology list, here are a few new additions: tours of the National Museum in Bangkok and the Sangiran Museum in Central Java, and the Intramuros of Manila
The interactive Sangiran Museum of Early Man in Central Java is based around the Sangiran Unesco World Heritage Site. It features multiple locations around the museum to explore, and also has embedded videos and 3D models to explore.
The National Museum in Bangkok also has a virtual tour section of exhibitions halls from around 2014 and 2015, this is neat, because these exhibitions are no longer on display physically but you can still visit them virtually.
The Intramuros Administration has a section in Google Arts and Culture where you can view exhibits online, as well as explore areas of the walled city in a virtual reality setting/
As usual, a full and updated list of sites you can visit virtually can be found in the Resources page.
