As an astounding landmark in the capital city of Iceland, Hallgrimskirkja Church is the highest building in downtown Reykjavik, Not only is it visible from almost every corner of the city, it’s also the tallest church in Iceland. Samúelsson, the architect, was fascinated by the shapes that formed from cooled lava and dreamed up a design inspired by basalt rocks. When he first proposed the blueprint, his unconventional concept raised eyebrows. However, after 40 years in the making, it is now one of the city’s landmark symbols and a must-see for travelers.
