St Mary's has an area of
By air, the island is served by St Mary's Airport. Fixed-wing aircraft services are scheduled, operated by Isles of Scilly Skybus, to and from Land's End, Newquay, and (except in winter) Exeter. Helicopter services were operated by British International Helicopters, from Penzance Heliport; this service, which started in 1964 (then operated by BEA Helicopters), ceased at the end of October 2012.
Helicopter flights resumed in 2020 with the launch of the Penzance Helicopter service.
By sea, the Isles of Scilly Steamship Company provides a passenger and cargo service from Penzance, which is currently operated by the Scillonian III passenger ferry, supported by the Gry Maritha cargo vessel. The other islands are linked to St. Mary's by a network of inter-island launches. The main harbour of St Mary's (and the Isles of Scilly) is at Hugh Town, and is called St Mary's Harbour. Further slipways and small quays exist around the island, at natural harbour sites, such as at Old Town, Pendrathen, Watermill Cove, and Porthloo.

There has been an RNLI lifeboat station on St Mary's since 1837. The first two lifeboats were kept in a boathouse on the town beach at Hugh Town. Following closure in 1855 the lifeboat station was re-opened in 1874 and a boathouse was built on the beach at Porth Cressa. In 1899 a new boathouse and slipway were built at Carn Thomas and the first motor boat arrived in 1919.
The lifeboatmen of St Mary's have earned 26 RNLI medals for bravery, comprising one gold, nine silver and 16 bronze, the last awarded in 2004.
Churches
There are Anglican churches such as St Mary's Church, St Mary's and St Mary's Old Church, St Mary's.
John Wesley preached here on 13 September 1743. The Wesleyan Methodist Society was established in 1788 and the first chapel erected in 1790. This was replaced in 1828. The present Methodist church was built in 1899 by A.J. Trenear in Hugh Town and is part of the Isles of Scilly Methodist Circuit.
Cornish Wrestling
Captain James Williams White (1826-1903), the champion Cornish wrestler, was born on St Mary's and after emigrating lived in Burra, South Australia, from 1856.
Landmarks
Telegraph Tower
The tower on Newford Down, now known as Telegraph Tower, was built in 1814 to serve as an Admiralty Telegraph Station, but it had closed by 1816. The building then reverted to the custody of the landowner - the Duke of Leeds. In 1831 the site was taken over by the Coastguard as a subsidiary to the main station situated on the Garrison. In 1903 a wireless mast and receiving office were built nearby, and in 1908 a telegraph house was erected on the tower's roof. The wider site was developed into a modern radio transmitting and communications site by the late-C20. The tower is now a private residence. It was at this tower about 1898 that Guglielmo Marconi heard wireless signals transmitted from Porthcurno, a distance of 30 miles. It was used by Radio Scilly for broadcasting.
Note: To strengthen Scilly's defences Major Daniel Lyman proposed the construction of three gun towers in 1803, each armed with a 32-pounder carronade on top. The presence of three towers on St Mary's, in the heart of the Garrison, on Buzza Hill and at Newford Down, has led some writers to link them to Lyman's proposal. However, his proposal was never enacted, and the three towers have different origins. on the coastal path between the airfield and Porth Hellick Bay.
The Garrison and Star Castle
Star Castle is at the centre of a fortification system around the west side of St Mary's known as the Garrison. The walls of the castle take the shape of an eight-pointed star. It comprises an outer wall around the outcrop of Hew Hill, protecting the town and the castle, with strategically placed gun batteries at regular intervals around the outer wall, allowing covering fire at all angles. A redundant windmill was converted after 1831 into Garrison Tower as a lookout tower for HM Coastguard.
The Star Castle was built in 1593 by the Surveyor of the Royal Works and mapmaker Robert Adams (d.1595), under the direction of Francis Godolphin, following the Spanish Armada of 1588. Fearing another Spanish invasion, in May 1593 Queen Elizabeth I ordered the construction of a fort and two sconces as a lookout for any intruder ships.
In 1740 Master Gunner Abraham Tovey transformed the Garrison building walls with gun batteries, including Colonel Boscawen's Battery, in a circular shape following the coast line of The Hoe. Star Castle is now a hotel.

Peninnis Head
The 14 metre metal tower lighthouse on Peninnis Head was built in 1911 as a replacement for the 1680 lighthouse in the centre of St Agnes. The lighthouse was converted from acetylene gas to electricity in 1992 and the original range of 17 nautical miles was reduced to nine in 2011. The headland is within the Isles of Scilly Area of Outstanding Natural Beauty and part of the Heritage Coast. It is also a Geological Conservation Review site for its Quaternary geomorphology and was first designated a Site of Special Scientific Interest (SSSI) in 1971 for both its biological and geological interests.
Porthellick Cove

Porthellick Cove contains a memorial to mark the spot where the body of Admiral Sir Cloudesley Shovell was washed ashore after the 1707 Scilly naval disaster. This was one of the greatest maritime disasters in British history, when four ships (Association, Firebrand, Romney and Eagle) with nearly 2,000 sailors were lost.
