Greater Cochin Development Authority (GCDA) is the statutory body overseeing the development of the City of Kochi in the state of Kerala, India. Technically, GCDA oversees the development of the major part of Greater Cochin area which consists of the Cochin Corporation, nine surrounding municipalities (Thrippunithura, Thrikkakara, Aluva, Kalamassery, Maradu, Eloor, North Paravur, Angamaly, and Perumbavoor) and 25 intervening panchayats (Chellanam, Kumbalanghy,Cheranelloor, Varappuzha, Chennamangalam, Kadamakkudy, Kadungalloor, Alengad, Chengamanad, Nedumbassery, Chottanikkara, Choornikkara, Edathala, Kumbalam, Kottuvally and others) covering an area of 632 km2. This has a population of 2,589,038 (2001 census).
GCDA is one of the two development authorities in Kochi, the other being GIDA which oversees development in the islands towards west of the Kochi mainland, and north of the harbour, covering a total area of 100 km2. The Marine Drive is one of the most significant projects that GCDA has ever undertaken. The largest stadium in Kerala with a seating capacity of 75000, have been constructed by GCDA.
Fort Kochi is a region in the city of Kochi in the state of Kerala, India. This is part of a handful of water-bound regions toward the south-west of the mainland Kochi, and collectively known as Old Kochi or West Kochi. Adjacent to this is Mattancherry.
In the BC period, the region that is today known as Kerala was covered by mangrove woods. Turf and sand banks were created with the rise in sea-level which formed the shape of the coastal area as we see it today. The name Cochin implies "co-chin", meaning "like-China". It looked like China when the Chinese came to the region during the 14th century and installed Chinese nets. Mattancherry is the nerve town of old historic Cochin. In old Malayalam it is maadan-cherry, cherry meaning town. Maad or cow was the stamp of Old Royal Fort of Rajah of Cochin, who built his palace after the fall of Kodungallur or Mussaris port due to a gigantic tsunami in 1341 AD. The Perumpadappu Swaroopam or the Forte of Rajah had its palace on the banks of the Calvathy River. Due to frequent wars between King Zamorin of Kozhikode and the western colonial forces, the Rajah left the place for Tripunithura. The king had his vaishnav leanings and cow or maadu was their symbol.
In 1967, these three municipalities, along with a few adjoining areas, were amalgamated to form the Corporation of Cochin.
