Restored in 2001 and famously known as The Gate of Heaven among tourists, Pura Penataran Agung Lempuyang sits 600 meters (2,000 ft) above sea level on Mount Lempuyang's slope. The mountain is divided into three sections mirroring Balinese cosmology: the base as Sang Ananta Bhoga (Brahma's mount), the middle as Sang Naga Basukih (Vishnu's mount), and the summit as Sang Naga Taksaka (Shiva's mount). The most sacred point is where Pura Lempuyang Luhur stands, while Pura Penataran Agung occupies the middle part, and Pura Dalem Dasar Lempuyang stands at the base.

Pura Penataran Agung Lempuyang's temple grounds are structured into three areas: the outer sanctum (jaba pisan or nistaning mandala), the middle sanctum (jaba tengah or madya mandala), and the inner sanctum (jero or utamaning mandala). Entry into the outer sanctum is marked by a split gate known as Candi Bentar, painted white. Within this area are several bale pavilions, including the bale gong for storing gamelans and the bale kulkul housing the prayer drum. Access to the middle sanctum is through three paduraksa portals, with the central portal typically closed except during major festivals.

The staircases leading to these portals are adorned with dragon (naga) mythical figures, and along the climb, sculptures inspired by the Ramayana epic, such as Arjuna, Bima, and Yudhistira, are found. At the highest level stands the statue of Krishna, Vishnu's earthly form. The inner sanctum (jero) is the most revered part of the temple, housing Meru Towers and Pelinggih Shrines dedicated to various gods and local deities. Padmasana Shrines shaped like empty stone thrones honor the highest gods of the Hindu pantheon, including Sang Hyang Widhi and the Gods of the Trimurti.

At its heart lies an impressive eleven-tiered fountain, complemented by numerous ornate sculptures throughout the expansive grounds. The vicinity of Tirta Gangga is renowned for its picturesque rice terraces, adding to the allure of this cultural and historical gem.
