Berlin Cathedral vs Inco Superstack

Informations

The Berlin Cathedral (German: Berliner Dom) is a Protestant church and dynastic tomb on the Museum Island in Berlin.

Built from 1894 to 1905 by order of German Emperor William II according to plans from Julius Raschdorff in Renaissance and Baroque Revival styles, the listed building is the largest Protestant church in Germany and one of the main dynastic tombs in Europe. In addition to church services, the cathedral is utilized for state ceremonies, concerts and other occasions. Since the demolition of the Memorial Church (Denkmalskirche) on the north side by the East German government in 1975, the Berlin Cathedral has consisted of the large Sermon Church (Predigtkirche) in the center, the smaller Baptismal and Matrimonial Church (Tauf- und Traukirche) on the south side and the Hohenzollern crypt (Hohenzollerngruft), which covers almost the entire basement.



Damaged during the Allied bombing in World War II, the cathedral's original interior was restored by 2002. Currently there is discussion about restoring the historic exterior too.

The Inco Superstack in Sudbury, Ontario, with a height of 381 metres (1,250 ft), is the tallest chimney in Canada and the Western hemisphere, and the 2nd tallest freestanding chimney in the world after the GRES-2 Power Station in Kazakhstan. It's also the second tallest freestanding structure of any kind in Canada, behind the CN Tower but forward of First Canadian Place. It's the 40th tallest freestanding structure in the world. The Superstack is situated on top of the biggest nickel smelting operation in the world at Vale's Copper Cliff processing centre in the city of Greater Sudbury. In 2018, Vale declared that the stack will be decommissioned and dismantled beginning in 2020. On July 28, 2020, Vale declared that the stack had been officially taken out of service, but would remain operational in standby mode for two more months as a backup in case of a malfunction in the new system, after which the dismantling of this Superstack will begin. In addition to further reducing sulfur dioxide emissions by 85 percent, the decommissioning of the pile is expected to cut the complex's natural gas consumption in half.
