Tower of Refuge

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.

Douglas Lifeboat Station is located at Battery Pier, Douglas Head, in Douglas, capital of the Isle of Man, a British Crown Dependency. Douglas and the Isle of Man holds a special place in the history of the Royal National Lifeboat Institution (RNLI), previously the Royal National Institution for the Preservation of Life from Shipwreck (RNIPLS), as this was the home of its founder, Sir William Hillary, 1st Baronet, (1771–1847). The first Douglas lifeboat was funded by the Duke of Atholl, Governor of the Isle of Man, and arrived in 1802. A lifeboat station operated by the RNIPLS was opened in 1825. The station was re-established by the RNLI in 1868. The station currently operates one of the last two Mersey-class lifeboats still in active service, 12-22 Ruby Clery (ON 1181), on station since 2022.

The Isle of Man Sea Terminal (Manx: Boayl Troailtee Varrey Vannin) is the arrival and departure point for all passenger and car ferries operating to and from the Isle of Man, and is located in Douglas, the island's capital. It is one of the two main gateways to the Isle of Man, the other one being the Isle of Man Airport. It is operated by and is the main hub for the Isle of Man Steam Packet Company, which runs year-round sailings to Heysham, and seasonal sailings to Liverpool, Belfast and Dublin in the summer and Birkenhead at weekends in the winter.The Sea Terminal is located on the near side of Douglas Harbour, closer to the promenade. It also houses the Isle of Man Welcome Centre, which is the main visitor centre for the island, a theatre box office, and the Department of Infrastructure's Licensing Office. The Douglas Harbour Control Unit is also located on the upper level of the Sea Terminal.

Manx Radio (legally Radio Manx Ltd.) (Manx: Radio Vannin) is the national commercial radio station for the Isle of Man. It began broadcasting on 29 June 1964, almost ten years before legal commercial radio was licensed in the United Kingdom. The Isle of Man, having its own government and laws, was not subject to the rules prohibiting commercial broadcasting in the UK. However, the Manx Government still had to apply to the UK's General Post Office for a frequency and for permission to broadcast. First requested in 1960, a licence was eventually granted in May 1964. It was allocated an FM frequency of 89.0 MHz and a comparatively low power of 50 watts. In October 1964, an additional frequency of 1594 kHz AM was allocated to the station to provide greater coverage, although again at a limited power of 50 watts. It broadcasts primarily in English with several hours per week of Manx language programming. As of September 2023, the station broadcasts to a weekly audience of 26,000 listeners, according to RAJAR.

Douglas Southern Electric Tramway (Manx: Raad Yiarn Lectragh Jiass Ghoulish) was a standard gauge tramway between the top of Douglas Head on the Isle of Man and the nearby resort of Port Soderick. The route ran atop the cliffs and crossed a number of viaducts and bridges.

The Grand Union Camera Obscura was built during the 1890s and is located on Douglas Head near the Lighthouse. The building is a tourist attraction that offers a unique view of its surroundings. Using several lenses and mirrors, it reflects a unified, panoramic view of the surrounding area that is split into small digestible scenes and projected onto large white screens within the dark confines of the building. This optical effect is achieved by the apparatus known as camera obscura.

Douglas Head Lighthouse is a lighthouse at Douglas Head on the Isle of Man located between England and Ireland. The lighthouse was established in 1857, although the vicinity was under the control of the Isle of Man Harbour Board from 1832.

The white tower is 20 metres (66 ft) in height and its base is at an elevation of 12 metres (39 ft). The lighthouse staircase has 71 steps and the light has an average range of 24 nautical miles (44 km). The lantern is composed of eight brilliant reflectors made of pure silver built in 1831. The light flashes white every ten seconds.
