The Northern segment of the Margao Municipal Garden was developed by Abdul Javerbhai Mavany in memory of his late father Javerbhai Ramjee. It was named after H. H. The Aga Khan who visited Goa just before liberation. The park was inaugurated by Goa’s last Portuguese Governor General, Vassalo e Silva, on 25 December 1959.
The flowers of the Golden Shower Trees (Cassia fistula) which adorns the park are the floral emblem of the state of Kerala and the national flower of Thailand.
