We went the a medieval-like fortress in Old Delhi called Red Fort. It has a 10 meter deep overgrown moat around it that has been dry since 1857. Drawbridges were once the main means of entry. The walls of the fort extend for 2km. Shah Jahan constructed the fort between 1638 and 1648. Back in the day- it was overflowing with gold and jewels. It was described as paradise and heaven on earth. Invading armies came at different times in history and stripped the buildings of all their glory- but they still remain beautiful today.
