It's a shame, but at the same time it makes it easier to get noticed...
In a museum situation there is always tension between preservation and restoration. The aim of a museum isn't to have a (boring) collection of items restored to brand spanking new condition. It is to record the story associated with each object, and that story can be lost by restoration. A particular bit of damage might be significant as a record of the events at the time, for example, marks on a building due to a record flood, a bullet hole due to a particular battle or a significant piece of graffiti. It gets complicated when one has to choose which story to tell, such as a painting with two layers. Which to display?
Granted that the description paints the clock as being in a state of decay, not preservation, so the above argument probably doesn't apply in this case. There's an argument though that UX shouldn't be blinding going around fixing everything!
On a tangent, there are many tunnels under Chicago, too, which has neen used during the Prohibition. Any local HNers who has been to these?
Thanks for the link!
In the 60's the young generation started organizing crazy parties (Especially in the famous "Salle Z" or "Z Room") with hundreds or thousands of people. It has been a widely illegal and famous way to organize hazing sessions for Paris schools and universities.
Now cataphiles are all over Paris which has more than 280km of catacombs. It takes hours to go from one place to another. Some are more visited than others and easier to access. It is a common (and fun) thing to do when you are young in Paris, you can also easily find the movie theaters and get the maps from internet.
People sometimes get caught, the police is patrolling but the risk (~60€) is low.
I doubt i'd suggest it for tourists unless you have a friend who knows where to go. It takes hours to find an entrance and sometimes more than 4hours walk to find "nice" and historical areas.
