The Struve Geodetic Arc is a chain of survey triangulation points that stretch from Hammerfest in Norway all the way to the Black Sea. The imaginary lines go through ten countries and over 2,820 kilometres. Carried out between 1816 and 1855 by the astronomer Friedrich Georg Wilhelm Struve, this survey represented the first accurate measuring of a long segment of a meridian, helping establish the exact size and shape of the planet. Sweden has seven measurement points and four of them are on the World Heritage List (on the mountains Tynnyrilaki, Jupukka, Pullinki, and Perävaara). The mountaintop unveils an expansive view.

Partially inspired by the St Paul’s Cathedral in London, this one maintains a colonial style of architecture. Saint Mark Cathedral is located on the busy Mahatma Gandhi Road, boasting a magnificent dome, Roman arches and the best-maintained church bells in the city.

To get into this national park, foreigners must pay a toll fee. This place sits magically on the top of mountains that have been used to build the temples of Angkor Wat. The water running from the beautiful waterfall is said to be holy and locals often bring a bottle of it with them home.
