Engineering is the art of directing the great sources of power in nature for the use and convenience of man - Thomas Tredgold. Angkor Wat is an amazing work of Khmer architecture. It shows that symmetry and repetition were very important to Khmer design: galleries with columns, towers, curved roofs, tympanums, steps and the cross-shaped plan occur again and again. Spreading over 30 years, the construction of the temple required about 6 to 10 million blocks of sandstone with an average weight of 1.5 tons each. The blocks were transported from Mount Kulen, a quarry approximately 40 km to the northeast, thru a series of canals.
The Basílica i Temple Expiatori de la Sagrada Familia (English: Basilica and Expiatory Church of the Holy Family) is a large Roman Catholic church in Barcelona, designed by Spanish architect Antoni Gaudí. Passion Facade , on the theme of Christ’s last days and death, was built between 1954 and 1978 based on surviving drawings by Gaudí, with four towers and a large sculpture-bedecked portal.
