Etymology.
Gurunagar, also spelled as "Kurunagar" derives its words from "Kuru" and "Nagar" (Urban centre in Tamil). The word "Kuru" is a clans name used by the Karaiyars also known as "Kurukulam," who make up majority of Gurunagar.
Karaiyur, as it was earlier known as stems from the Tamil words "Karai" (coast) and Ur (village). Karaiyur was marked in the Dutch maps as "Cereoer." 
History.
The earliest settlers of Jaffna, were according to local legend, a musician and his kinsfolk. The surmised place they first settled is in the area surrounding Gurunagar and Colombuthurai. The Columbuthurai Commercial Harbor situated at Colombuthurai and the harbor known as ‘"Aluppanthy"’ situated previously at the Gurunagar area seem as its evidences.
The navy of the Aryacakravarti dynasty were manned and officered by the people of Gurunagar. The "Pattinathurai" of Gurunagar was a port for foreign vessels. It is surmised that it was here the Moroccan explorer Ibn Battuta, saw fleet of ships that belonged to the Aryacakravarti kings. The Maniagar and Adappans of Gurunagar served as one of the headmen of the Jaffna ports. 
The western section of the Jaffna Kingdom was allotted by the Karaiyars of Gurunagar. There existed a smaller fort in Colombuthurai and one at "Pannaithurai" near Gurunagar. In 1560, the Portuguese forces with 77 ships arrived in Gurunagar and defeated the Tamil army governing there before proceeding further to Nallur.
The Cathedral of Jaffna in Gurunagar was constructed over an already existing smaller chapel. The chapel was constructed as the place where the Jaffna king Cankili I killed his own son for converting to Catholicism. 
Starting from the early 1920s, was the Gurunagar land reclamation scheme started, starting from modern "Beach Road" to "Reclamation Road."
