Brussels has been celebrating the treaty that created the EU and the single currency.<br /><br /> Well, EU officials have anyway. <br /><br /> Euronews asked several passers-by on Tuesday and not many were able to come up with the reason why the Dutch town of Maastricht is so important. <br /><br /> The treaty came into force in 1993 and laid the stages of monetary union, which led up to the physical launch of the euro on January 1 2002.<br /><br /> But it was not without some problems.<br /><br /> The Danes rejected it in a referendum, before eventually accepting it after some revisions.<br /><br /> France also approved Maastricht by a wafer-thin margin.<br /><br /> In Germany, the constitutional court ruled that the government could enforce the treat, but in the UK, it got through parliament amid a brutal row between Conservative MPs.<br />
