Kosi Lattha: Ramnagar's 100-Year-Old Flood Defense, an Engineering Marvel

• Ramnagar's Kosi Lattha, a massive embankment built in 1926 during British rule, celebrates 100 years of protecting the city from Kosi River floods.
• Constructed after devastating floods in 1910 and 1913, the Lattha was designed to control the Kosi River's overflowing waters and protect agricultural land and villages.
• Built with stone, lime, and surkhi, this nearly three-quarters of a kilometer long protective wall is considered an impregnable fort, earning it the nickname "China Wall" by locals.
• The project also included the construction of three vital canals (Ramnagar Belgarh, Ramnagar, and Chilkiya) for irrigation, demonstrating a farsighted plan for agricultural and economic development.
• Local residents are demanding that the Kosi Lattha be formally declared a heritage site, recognizing its historical significance and enduring role as Ramnagar's lifeline.
