AMBER PALACE
One of the top tourist attractions of Jaipur, the huge Amer Palace Fort sits atop a small hill, and is located at a distance about 11 km from the main city. The magnificent Amer Fort is an extensive palace complex that has been built with pale yellow and pink sandstone, and with white marble. The fort is divided into four main sections that are graced with their own courtyards.
As you arrive at the Amer Fort, you will enter through the Suraj Pol; unless you arrive by car, then you enter via the Chand Pol. Both these gates open into the Jalen Chowk, which is the main courtyard, where in earlier times, returning armies used to display their plunder to the people. The fort has a number of sections, including the King’s quarters, the zenana (where the women lived), gardens, temples, etc.
There are a lot of attractions for one to see at the Amer Fort, including the diwan-e-aam, such mandir, and the Sheesh Mahal. Amer Fort is also home to some underground tunnels that connect Amer to Jaigarh Fort. A part of these tunnels has been restored, and is now open to public as well. 
Jantar Mantar
The Jantar Mantar is a collection of 19 astronomical instruments built by the Rajput king Sawai Jai Singh, the founder of Jaipur, Rajasthan. The monument was completed in 1734.
It features the world’s largest stone sundial, and is a UNESCO World Heritage Site. It is near City Palace and Hawa Mahal.
The instruments allow the observation of astronomical positions with the naked eye.
The observatory is an example of the Ptolemaic positional astronomy which was shared by many civilizations.
