Gunung Gangsir Temple can also be called Kebon Temple because it is located in Dukuh Kebon Candi, Gunung Gangsir Village, Beji District, Pasuruan Regency, East Java. The name of this temple is still a myth of local residents, namely that the name 'mountain' is taken from the existence of this temple building in the past which was surrounded by mountains. Meanwhile, the word 'gangsir' (Javanese: nggangsir) means digging a hole below the surface of the ground. According to local residents, this name appeared when one day someone tried to 'move down' this mountain to steal valuable objects in this temple building. So this temple building became known as Gunung Gangsir Temple. The temple building, which is made of brick, has 4 floors, with the two ground floors being the actual body and roof of the temple. The ground floor plan is rectangular with a protrusion on the east side, in the opposite direction to the location of the stairs. The plan of the body and roof of the temple is also rectangular, but in this section the four sides of the walls of the temple have a slender protrusion area. Now the condition of the temple is in ruins, and almost all corners of the floors are damaged, as well as the horizontal parts where the floors meet, while the top of the temple has disappeared. As a result of this damage, the Gunung Gangsir temple building looks like a pyramid whose roof has been cut off. Not much information can be obtained regarding the temple which is said to have been built during the reign of King Airlangga, namely around the 11th century AD. Although it is thought to date from an earlier period before the reign of Singasari, Gunung Gangsir Temple was built using brick, not andesite. . Regarding the function of Gunung Gangsir Temple, no clear information is available. The local community has its own version regarding the purpose of building this temple. According to them, Gunung Gangsir Temple was built as a tribute to Nyi Sri Gati, nicknamed Mbok Randa Derma (generous widow), for her services in building an agricultural community in the area. Nyi Sri Gati is a figure in local legend. In ancient times, people in that area were not familiar with farming. They like to wander and their main food is grass. One day, the grass which was their staple food began to run low. At that time a woman came, who knows where she came from, named Nyi Sri Gati. The woman invited the travelers to pray, asking Sang Hyang Widi for guidance on how to overcome the food shortage they were experiencing. Not long afterward, a group of sparrow birds came carrying grain and dropped it near the travelers. The rice that fell was then planted by Nyi Sri Gati. Several months later, the Nyi Sri Gati plants could be harvested. Nyi Sri Gati then pounded her harvest to make rice, which she then processed into rice. Nyi Sri Gati then taught the nomads how to farm. Since then, the nomadic people have settled and lived from farming. They make rice their staple food. Some of the rice that the bird dropped turned into jewels which made Nyi Sri Gati very rich. Gunung Gangsir Temple has never undergone comprehensive restoration. Although the entire Gunung Gangsir Temple building still stands majestically, many parts have been destroyed. It is said that this temple suffered heavy damage during the Japanese colonial era. Many of the decorations on the temple walls were taken by the Japanese army to finance the war. After Japan passed, residents carried out modest repairs without having sufficient knowledge about temple restoration. Some pieces of brick or wall hangings look very different from where they are attached. It looks like the actual location is not in that place. The foot of the temple is rectangular with a size of around 15 x 15 m2. The building height reaches around 15 m. Inside the temple there is a room that is said to be quite spacious, so it can accommodate 50 people. The entrance to the room is located to the west, about 5 m from the ground. To reach the door there is a fairly wide staircase, which extends far to the west. Unfortunately the stairs have been destroyed, making it difficult to climb. On the walls to the right and left above the door there are niches that look like places to place statues. The niche on the south side has been destroyed, while the remains on the north side are still visible. Currently, the roof of the temple is curved with a blunt tip like a mountain peak. The top of the roof has been destroyed, but the roof support can still be seen. From behind, the temple building looks like a small hill made of bricks. There are no niches where statues can be placed.
