'''Dolphin Lighthouse''' (or '''Dolphin Rock Light''') is one of the three [[lighthouse]]s in the [[Mumbai harbour]] off the coast of [[Mumbai]], [[India]]. It is near the [[Gateway of India]] and is controlled by the [[Indian Navy]]. To honour military personnel, a [[21 gun salute]] is held every time a warship sails out of the Mumbai harbour with The Admiral of The Fleet. This lighthouse is also illuminated during [[Navy Day]] celebrations which happen during the first week of December every year.<br />
<br />
== History ==<br />
The lighthouse is one of the oldest in [[Mumbai Harbour|Bombay Harbour]]. It was first lit in 1856 to mark the Dolphin Rock shoal and ensure safe passage of ships approaching Mumbai port.<ref name="Heikell 2019 p. 160">{{cite book |last=Heikell |first=R. |title=Indian Ocean Cruising Guide |publisher=Imray, Laurie, Norie and Wilson Limited |year=2019 |isbn=978-1-84623-889-5 |url=https://books.google.com/books?id=vheQDwAAQBAJ&pg=PA160 |access-date=14 May 2019 |page=160}}</ref><br />
Dolphin Lighthouse formed part of a chain of harbour lights developed by the British.<ref>{{Cite web |last=Menon |first=Smitha |date=2015-10-28 |title=Should you sail out on a hot Sunday morning? |url=https://www.cntraveller.in/story/should-you-sail-out-hot-sunday-morning/ |access-date=2025-06-29 |website=Condé Nast Traveller India |language=en-IN}}</ref> It originally displayed a white‑green occulting light with a 4‑second cycle, visible out to about 7 nautical miles. The lighthouse has always been unattended (automated) and does not carry resident keepers. Over time its role has diminished with modern navigation systems. Today it is reported to be unlit and no longer serves as an active aid to navigation.<ref name="Shankar">{{Cite news |last=Shankar |first=Anuradha|title=The lighthouses of Mumbai harbour |url=https://timesofindia.indiatimes.com/travel/destinations/the-lighthouses-of-mumbai-harbour/articleshow/32420508.cms |access-date=2025-06-29 |work=The Times of India |issn=0971-8257}}</ref><br />
<br />
== Design and Technical Features ==<br />
Dolphin Lighthouse is built of stone in a plain cylindrical form, capped by a [[Lantern|lantern chamber]] with a balcony. The tower is approximately 18&nbsp;m (59&nbsp;ft) tall. It originally exhibited a group-flashing light: four flashes every 20 seconds, showing a white sector visible to 11 nautical miles and a red sector to 5 nautical miles. Photographic surveys note its focal plane about 11 m above sea level with the red sector covering bearings 147–236° and 270–360°, and white sector 236–270°.<ref>{{Cite web |title=India - Mumbai / Dolphin Rock light - World of Lighthouses |url=https://www.lightphotos.net/photos/displayimage.php?album=138&pid=50099 |access-date=2025-06-29 |website=www.lightphotos.net}}</ref> These characteristics ensured it could be seen by ships at moderate range in the harbour approaches. The tower itself is unpainted stone, with the lantern room painted white.<ref name="Shankar"/><br />
