Royal Observatory Greenwich

Sharing is caring!

Royal Observatory Greenwich – The meridian (0° longitude) that divides the Earth in the eastern and western hemispheres passes by here. Millions of visitors take pictures by placing a foot on each side. In 1884, Greenwich Mean Time became the basis for measuring the time for most of the world, in accordance to an important international agreement.

The original building is the Flamsteed House, designed by Wren. It has an octagonal room on top, hidden by squared walls outside and topped by two towers. Upon one of them there is a ball attached to a rod that falls every day at 13:00 hrs, since 1883, so that the sailors of the Thames and manufacturers set their clocks timers. Flamsteed was the first Royal astronomer, appointed by Charles II. Greenwich was the official observatory of the government from 1675 to 1948, as from when the astronomers moved it to Sussex. Today, the RO is also home to London’s planetarium, the Harrison timekeepers and the UK’s largest refracting telescope.

It cannot be denied that one of the tourist attractions of one country is a museum of whatever kind. A country with a number of museums is said to have wealthy and excellent history. Aside from this, one country can be able to educate not only its citizens but visitors and travelers as well regarding the things that might have happened before. People these days can be able to have a clear idea of the events during the past decades and even centuries. They can also learn almost everything about the world.

For instance, The Royal Observatory in London is depicting the navigation and history of time. This museum was designed by Christopher Wren and was founded way back in the year 1675. This museum was founded to calculate the precise longitudes for navigational purposes. These days, the Observatory is a branch of another museum in London which is the National Maritime Museum. It has a permanent exhibition that shows navigation and history of time. Aside from this, it holds the only planetarium in London, attributing the Europe’s first digital projector. Huge space is dedicated to the Weller Astronomy Galleries which is found in the observatory’s South Building. This is where the visitors can be taught how planets and stars are born. They can also unravel some of the other wonderful mysteries of the universe.

Collectively with the most recent planetarium, visitors can also view an antique orrery that came from the 19th century. This demonstrates the movement of the planets. This only means that visitors can grasp how the different planets and stars of the universe move. This museum is perfect for school tours focusing on science classes. School children, for example, can have a clear picture of what they are learning on their science classes. What is good with this museum that it opens from Monday to Sunday so visitors can go there during their leisure time.
