Despite the regular use of domes, the Minaret is the only architectural feature that is synonymous with mosques. Above are two examples of highly decorated minarets, separated by just short of 900 years. The much discussed Brick Lane minaret, constructed at the end of 2009 is a stainless steel structure, rising up to 90ft in amongst a highly dense part of London. The minaret is the first religious structure added to a building that has been used to house worshipers of different religions over around four centuries and has been accused of pointlessly labeling a structure that does not require it. It is however a beautifully worked piece of metal sculpture. The Islamic pattern is clinically cut using some sort of Computer Aided Manufacturing (CAM), most likely a water jet cutter; as suggested for cutting the Wallpaper Balustrade. The other, the Kalyan Minaret located in Bukhara, Uzbekistan. Constructed in 1127, this looks like a possible precedent for the whole Brick Expressionism movement, with the brick used as decoration and well as structure.
