Prince Karan Singh was asked to act as the envoy to the Mughal court. During this time a friendship developed between the Mughals and the Sisodiya rulers. As is the norm of the Rajputs the Mughal prince was treated with hospitality and a domed pavilion was built for Shah Jahan. The interiors of the palace were lavishly done. A throne and a mosque were built for the guest. It is said that the pietra dura work in the interior of the palace later inspired Shah Jahan while he commissioned the construction of Taj Mahal.
Jagmandir is built in sandstone. The palace flaunts designs in onyx, jasper and agate. This palace was further extended by Jagat Singh. He added women's quarters and it is known as zenana. He also named the palace after him. Till date the palace is known by his name-Jagmandir. As one proceeds towards Jag Niwas eight elephant statues will lead the way. This part of the palace is known as the Gul Mahal. This section was built by Karan Singh during 1625 to 27.
Jagmandir in Udaipur is one of those rare monuments in Udaipur that reflect the Mughal influence on Rajasthani style of architecture.
