For those with a head for heights, visiting the Eiffel Tower in Paris is now more of an adventure than ever – thanks to a new glass floor offering a tantalisingly jaw-dropping view.<br /><br />It is part of a 30 million euro first-floor facelift for the famous monument. So what does it feel like to look 57 metres straight down?<br /><br />“Butterflies in my stomach,” said US tourist Aaron Smith from Hawaii. <br /><br />He said he was “scared” but “hoping they did a good job building it – hoping I’m not that one guy that falls down. It was fun though.”<br /><br />It means more people may stop on the first floor before heading to the top.<br /><br />“It is impressive,” said Spanish tourist Manuel Perez.<br /><br />“I didn’t know this part of the Eiffel Tower existed and it is really impressive. Looking down, I am speechless. Speechless.”<br /><br />Solar panels and a museum are also part of the renovation of the Eiffel Tower which has graced the Paris skyline since 1889.
