The name "Sion" is derived from the Marathi word "Sheev," which means boundary, as it marked the northern limits of Mumbai during the British colonial era. The area has evolved from a historic outpost into a densely populated urban locality, hosting diverse communities and cultural landmarks.In 1543, the Portuguese took possession of the largely uninhabited islands of Bombay, naming it Sião, after a biblical hill in Israel. The Portuguese gave the Jesuit priests the sole ownership of some of these islands. The Jesuits then built a chapel on the hill near the present-day railway station and named it after Mount Zion (Sion) in Jerusalem.
