Mantralaya is the administrative headquarters of the Government of Maharashtra in the city of Mumbai, India built in 1955. Mantralaya was earlier known as Sachivalaya. (Sachiv- Secretary, Alaya- House, meaning House of Secretaries, called Secretariat). The headquarters of most State Governments in India are called Secretariats. However, since Ministers (Mantri in Marathi) also sit in the same building and to underline the fact that Ministers are powerful in a democracy, the name was changed to Mantralaya in the early eighties.
