...detrimental effect on the city’s “exceptional” and “exquisite” architecture.
How bloody hypocritical of them. If they enforced their own rules about public signage and store fronts maybe we could experience this "exquisite" architecture they're talking about - rather than being subjected to the trashy lit-up signs from the 24-hour McDonald's branches and convenience stores all the way from Stephen's Green, up Grafton Street, around College Green and Westmoreland Street and up O'Connell Street.
There is nothing wrong with the picture above, in my opinion (the paving on the ground is a huge improvement than what's there at the moment). The cables can be hung from buildings (like on Harcourt Street) or poles similar to lampposts. If anything comes of this "demand" it'll be another few years before planning permission is even granted.
I'd rather have the Luas system with the cables than no system at all!
