Lumbung Temple is located a few hundred meters south of Sewu Temple in the sub-district of Klaten, Surakarta.
It remained unclear whether Lumbung is the legitimate name of the temple or the society from around temple called it because this temple is looks like a rice barn.
The ancient Buddhist building is a complex of temples made up of 17 structures, with the main temple in the middle surrounded by 16 additional shrines. Blocks of andesite fill the court of the temple.
The main entrance has a corbelled roof and a tunnel to the inside of the temple. The outer side of the wall is decorated with elaborately carved man-and woman-like sculptures of true human beings. The wall of the entrance door bears the sculptures of Kuwera and Hariti.
There are three compartments in which to put the statue of Dhyani Buddha on each of the north, west and south walls. Yet nine compartments have been found vacant.
The roof of the main temple, which is in a ruined condition and is believed to be in the shape of a stupa, resembles that of the ancillary temple. The court of the main temple is surrounded by crumbling walls.
The 16 auxiliary temples are located around and towards the main temple. Each of them is on a foundation 1 m high and 3 m2 long. The wall of the temple is simple without any ornament.
There is a stairway with stone guard rails on the east and right in front of the entrance. There is a bust of Kalamakara on the top of the door frame, with no lower jaw.
