Jaisalmer is a great place to simply wander. The old city was once completely surrounded by an extensive wall, much of which has sadly been ripped away in recent times for building material. Some of it remains, however, including the city gates and, inside them, the massive fort which rises above the city and is the essence of Jaisalmer. The main market area is directly below the hill, while the banks, the new palace and several other shops and offices are near the Amar Sagar Gate to the west.
Jaisalmer's past glories can be seen in its impressive golden fort on Trikuta Hill that dominates the horizon. The fort houses a township with markets, palaces, temples and exquisite carved sandstone havelis. Today, these homes are national treasures and art museums that are still inhabited. This last outpost of the Indian Republic is valued for its heritage as much as for its brave citizens, its people and culture, colourful festivals and crafts have placed Jaisalmer on the world tourist map.
