Sion Hillock Fort, Military fort in Sion, Mumbai, India.
Sion Hillock Fort is a military stronghold built on elevated ground with stone walls and pathways that wind upward. The site commands views over nearby salt pans and the surrounding landscape of the city.
Built between 1669 and 1677 by the East India Company, it served as a border marker between British and Portuguese territories. The fort was part of the larger strategy to secure control over the island region.
The Archaeological Survey of India maintains its Mumbai Circle office at the base of the hill, near the Pandit Jawaharlal Nehru Udyan garden.
The fort sits close to Sion railway station and is accessible by local buses and auto-rickshaws from around the city. Wear comfortable shoes since the path uphill involves walking on uneven ground.
Broken stone steps and scattered wall fragments remain at the site, preserving details of colonial-era military construction methods. These remnants reveal how builders engineered the fortification to withstand the conditions of this coastal location.
