When most people head over to Fatehpur Sikri, they’re usually busy gazing at the grand palaces, the massive Buland Darwaza, or the stunning marble tomb of Sheikh Salim Chishti. But tucked slightly off the main tourist drag sits one of the site's most curious structures, the Hiran Minar.Rising up above the plains on the edge of the old Mughal capital, this odd little tower has left historians confused for absolute centuries. Was it a loving tribute to a favourite elephant? A massive medieval lighthouse for weary travellers? Or maybe a giant milestone used to measure imperial distances? Whatever the real reason it was built, the Hiran Minar stands out as a seriously fascinating bit of Fatehpur Sikri, giving us a brilliant peek into the creative and engineering genius of Emperor Akbar's day.Image Credit: Canva
