I think that all of us on this site could be percieved as being overly critical of the Spire because we have been following it stage by stage during planning, construction, finishing and how it sits in it's surroundings etc, whereas the public have only been experiencing the Spire only in terms of it's finished outcome, they are unaware of the delays, the compromises, the lack of lighting etc etc, - and even then most people don't even look at it closely so they're not even critical of the finish!
But there is no question that the overall finish if far from satisfactory in 3 areas:
The lighting at the tip has been the least talked about.
The fact that the tip is made up of 6 different sections - divided by 5 'rungs' is a terrible asthetic cop-out as a result of engineering constraints, it is so contrived and obviously consticted by it's design, the rungs destroying the free flow of the light to the very tip of the sculpture.
And it is clearly evident that it is'nt the overall air quality in Dublin thats causing it to be so dirty, but rather the dust and dirt thats rising from O' Connell St and surrounding areas.
If you stand down Talbot or Henry St, the top third/half or so is shining clean in contrast with the lower half (and its nothing to do with shadows etc)
It is madness that it has'nt been cleaned since its erection, just madness.
