Bhopal boasts an undulating, uneven topography, defined by a series of low hills and valleys. The city's elevation averages around 500 meters (1,640 feet) above sea level, with its terrain gently sloping towards the north and east.
Key topographical features include: * **The Seven Hills:** Bhopal is often said to be built on seven hills, the most prominent being Shyamala Hill, Idgah Hill, Arera Hill, and Katara Hill. These elevated points offer panoramic views of the lakes and house many of the city's administrative buildings and upscale neighborhoods. * **The Lake Basin:** The Upper Lake was created by building an earthen dam across the Kolans River. It naturally drains into the Lower Lake, which sits at a slightly lower elevation. * **Rocky Outcrops:** The terrain features extensive sandstone outcrops, which historically provided building materials for the city's forts and monuments.
