Jaipur is a must on any itinerary to Rajasthan.  Like pretty much everywhere we've been in India, this city is bursting with colors to photograph.  Jaipur is called the "pink city" due to the majority of the buildings being painted a pinkish color. 
Our first stop was the city palace in the center of town.  This complex takes up several square kilometers full of beautiful arched doorways and beautiful carved details. 

Next to the palace was a unique observatory to visit called the Jantar Mantar.  This observatory is a garden type set up filled with various devices built out of concrete and stone dating back to the 1700s.

Including one of the largest sundials standing at 90 feet tall.  We loved the architectural feeling of these structures, making for great black and white images.
