[5] Jamnagar Municipal Corporation is planning to be develop riverfront on Rangmati – Nagmati river which cost of around 500 crore.

Jamnagar, historically known as Nawanagar (the new town), was one of the most important princely states of the Jadeja's in the region of Saurashtra.

According to bardic chronicles, impressed by Jam Lakhaji's role in at the siege of Pawagadh, Bahadurshah, the Emperor of Gujarat, bestowed 12 villages on him.

As Jam Lakaji was going to take possession of his new fief, he was treacherously killed by his cousins, Tamachi Deda and Hamirji Jadeja.

Hamirji's two sons Khengarji and Sahibji fled to Delhi to pay obeisance to the mughal Emperor Humayun.

When Jam Rawal heard of the two princes coming back to the Kutch with the imperial army, he started getting ready for the battle.

On one night, he dreamt of the goddess Ashapura who told him that as he had broken an oath taken on her name about not killing Hamirji, even though, he was the person responsible for the death of his father.

She had refrained from punishing him as he had at all other times honored her, but he was no longer to dwell in Kutch but cross the sea and reside in Kathiawar instead.

Jam Rawal bestowed the rule of Dhrol province to his brother Hardholji, who was later killed in battle, and the throne passed to his eldest son, Jasoji.

On the 7th day of the bright half of the month of Srawan, VS 1596 (August 1540 AD) on the banks of two rivers Rangmati and Nagmati, he lay the foundation of his new capital and named it Nawanagar (new town).
