The purpose of this study is to consider the principles of space formation of houses, villages and the cities focusing on the cosmology that decide physical arrangement. We selected Cakranegara in Lombok island, Indonesia, as a case study. Lombok island attracts us from several view points. As is well known, there runs Wallace line between Lombok and Bali island. Lombok island is also interesting in terms of religion. Most of Balinese are Hindu though over 90 % of the population in Indonesia are Muslim. Islam is dominant in Lombok island, but we can see the strong influence of Bali Hindu in the western part of the island. The fact that Hindu and Muslim people coexist in a small island is worthy to be investigated. Cakranegara is the city we firstly discovered if allowed to exaggerate its importance in the history of Indonesian cities. Karangasem Kingdom in Ball built Cakranegara as a colonial city in 18th century. Though Cakranegara was in the far east of Indian civilization at that period. We guess Cakranegara was constructed ideally based on the ancient idea of Hindu City. It is very interesting that Nagara- Kertagama; the Lontar paper that describe the Jawa and Majapahit kingdom in the 14th century, was discovered within the Kraton (palace) of Cakranegara. This paper is the first paper of a series of study on Cakranegara. This paper defined the purpose of study on Cakranegara and clarifies street's pattern, land division as the first step of a series of study on Cakranegara.
