Shravan Sud Poonam or Nariyeli Purnima is believed to be the foundation day of this holy city. As per the mythological reference in Sudama Charitra of Skand Puran of Shrimad Bhagavad, the present Porbandar city was named after Goddess Porav and was located along the river banks of Asmavati. The uniqueness of Porbandar city is that it is constructed of a special type of white soft stone-carved artistically and that is why this is popularly known as “WHITE CITY” also. Indian theology views Porbandar as the birthplace of Sudama, a friend of Krishna. For this reason, it is also referred to as Sudaamapuri or Sudamapuri. Onshore explorations in and around Porbandar brought to light the remains of a late Harappan settlement dating back to the 16th-14th centuries BCE. There is evidence to suggest that the Harappan legacy of maritime activity continued till the late Harappan period on the Saurashtra coast. The discovery of ancient jetties along the Porbandar creek signifies the importance of Porbandar as an active center of maritime activities in the past.
