THE NATIONAL MUSEUM OF THE PHILIPPINES
NATIONAL MUSEUM PLANETARIUM
Located in the Rizal Park Complex at P.Burgos St., Manila, the Planetarium reportedly has a small tektite display with tektites from different parts of Luzon, Borneo and Australia donated by Prof. Henry Otley Beyer of the Anthropology Division in the University of the Philippines.
I hope to visit this display shortly and report back.
I do not believe that any further displays of tektites can be found in the Philippines.
