The Tower of Refuge is a stone-built castellated structure which was erected on St Mary's Isle (also known as the Conister Rock) in Douglas Bay, Isle of Man, in order to afford shelter to mariners wrecked on the rock. The tower was constructed through the endeavours of Sir William Hillary, who had been instrumental in several rescues of sailors stranded on the rock, and which culminated in the heroic rescue of the crew of the Saint George Steam Packet Company steamer RMS St George, when it foundered on the rock in the early hours of November 20, 1830. Sir William personally contributed a high proportion of the costs and secured a substantial number of public contributions for funding the structure.

St Mary's Isle (also known as Conister Rock or the Tower of Refuge, Manx: Kione y Sker or Creg Voirrey) is a partially submerged reef in Douglas Bay on the Isle of Man. Prior to 1832 the rock was the property of the Quane family until John Quane, Attorney General of the Isle of Man, presented the rock to Sir William Hillary, in his capacity as President of the Isle of Man District of the Royal National Lifeboat Institution to build the Tower of Refuge. Since then the custody of St Mary's Isle has been held by each president of the local lifeboat association. The reef is not far from the ferry terminal. Its eastern part, the Conister Shoals, had to be blasted away when a new harbour breakwater was built in the early 1980s. The rocks are only fully submerged at spring high tides; they can be accessed very briefly on foot at low spring tides.

A later crane was built by Cowans, Sheldon of Carlisle (capacity 25 tons; carried on two four-wheel bogies; Works number 9057 of 1948 to Drawing 18087). The crane was owned by the Isle of Man Harbour Board and ran on 10 ft (3,048 mm) gauge.

Castle Mona is a former private residence later used as a hotel in Douglas, Isle of Man. The house was built between 1803 and 1804 for John Murray, 4th Duke of Atholl during his capacity as the Isle of Man's Governor General. Before 1850, Queen Victoria proposed buying it as a more suitable royal residence than Osborne House.After the hotel closed the building fell into disrepair, and subsequent to further disuse was sold at auction in 2018. In 2022 works were undertaken to demolish modern additions to the listed structure housing the bowling alley, nightclub and accommodation.

Cunningham's Camp Escalator was a moving seated escalator open c. 1919 to 1968 from a short distance behind the promenade in Douglas, Isle of Man, to Cunningham's holiday camp on Victoria Road. Although sometimes described as a 'chairlift', this was a ground-level escalator covered by a roof, albeit with seats, rather than an overhead chairlift as used in ski resorts. Cunningham's camp, one of the earliest holiday camps in the British Isles (pre-dating Butlins), opened around 1902 and initially had only steps leading to it from the seafront. The escalator was installed just after the First World War. It is thought to have been built by JT Skillicorn of Onchan. In 1938, a second escalator was provided, both working in only the up direction and running within a wooden shelter.The escalator last functioned in 1968, after which it was closed off but not demolished. In the 1990s the entrance was bricked over owing to the site being the target of vandalism. Since that time visitors can only view the large red brick and stone archway midway up Little Switzerland Road (site of today's Edelweiss Hotel). Behind the facade remain the turnstiles, and toilets with ceramic tiles and copper pipework, before reaching the approach steps to the escalator. The fascinating design is split into two parts, an "up" and "down" section, and each has its own set of moving wooden seats accompanied by steps for the more energetic. The system has been left to decay since closure, particularly since being bricked up. At the start of 2013 it was announced that it is to be demolished.
