On the sand plain, locally called "Segara Wedi" (lit. sand ocean), sits a Hindu temple called Pura Luhur Poten. The temple holds a significant importance to the Tenggerese scattered across the mountain villages, such as Ngadisari, Wonokitri, Ngadas, Argosari, Ranu Prani, Ledok Ombo and Wonokerso. The temple organises the annual Yadnya Kasada ceremony which lasts for about one month. The major difference between this temple and Balinese ones are the type of stones and building materials. Pura Luhur Poten uses natural black stones from volcanoes nearby, while Balinese temples are mostly made from red bricks. Inside this pura, there are several buildings and enclosures aligned in a mandala zone composition.
