Vaishali museum houses potsherds of NBP and PGW which include bangles, arrowheads, bones etc.
The excavation of various sites in and around Vaishali has yielded many relics and artifacts. To keep safe these artifacts, Archeological Survey of India has established a museum here called Vaishali Museum.
