Vinchu Kata is a traditional Indian fortification technique, primarily used in the construction of forts in the state of Maharashtra. The term translates to "scorpion tail," referring to the sharp, angular design that resembles a scorpion's tail. This architectural feature was strategically employed to enhance the defensive capabilities of forts, making it difficult for enemies to approach. The design of Vinchu Kata typically includes a series of sharp projections and walls that create a formidable barrier. This unique structure not only served a military purpose but also showcased the ingenuity of Maratha architecture during the 17th century. Forts like Raigad and Pratapgad exemplify the use of this technique.
