The museum also displays the Borobudur architecture and structure, also the documentation of restoration project conducted between 1975 and 1982 under UNESCO guidance.
The base level of Borobudur illustrating the first of the three zones of consciousness in Buddhist concept; the Kamadhatu or "desire realm".
However these 'hidden foot' of Borobudur with exquisite bas-reliefs is covered with additional encasement, the purpose of which remains a mystery.
The encasement base of the Borobudur temple was disassembled to reveal the hidden foot and the reliefs were photographed by Kassian Cephas in 1890.
[2] These include some dissasembled stone blocks, decorative panels, parts of reliefs and structures are stored in the open air field within museum compound.
However today this opinion is highly doubted, this unperfect Buddha statue was probably taken from elsewhere and the inner chamber of main stupa was more likely originally designed to be left empty to symbolize the ultimate concept of Śūnyatā (nothingness).
Terracotta water vessels, containers, jars and also other relics were discovered around Borobudur during restoration projects.
Other important exhibit also the 9th century large Buddha head, discovered in Selomerto, Wonosobo Regency, Central Java.
