today the grand bazaar is a thriving complex, employing 26,000 people visited by between 250,000 and 400,000 visitors daily, and one of the major landmarks of istanbul. it must compete with modern shopping malls common in istanbul, but its beauty and fascination represent a formidable advantage for it. the head of the grand bazaar artisans association claimed that the complex was in 2011 – the year of its 550th birthday – the most visited monument in the world. a restoration project starting in 2012 should renew its infrastructure, heating and lighting systems. moreover, the "han"s inside the market will be renovated and later additions will be demolished. this project should finally solve the big problems of the market: for example, in the whole bazaar there is no proper toilet facility. moreover, the lack of controls in the past years allowed many dealers to remove columns and skive walls in their shops to gain space; this, together with the substitution of lead (stolen in the last years) with concrete on the market's roof, has created a great hazard when the earthquake expected in istanbul in the next years will occur.
