good evening. it was nearly a mon historic notre dame cathedral in the heart of paris. millions of us watching live as a global treasure burned. and tonight the abc news exclusive look inside what remains. "world news tonight" anchor david muir up close with the relics that survived and the interview with the general in charge of bringing the church back to life. >> reporter: it was one month ago this week. the flames leaping from notre dame cathedral. the spire engulfed. and then the moment it came down. the spire collapsed along with the hearts of the people of paris and the world. the pictures are still haunting. so many were praying, asking would any of the cathedral be saved? the images of the firefighters racing to save the relics are still haunting. we traveled to paris to see what

remains. under a gray sky the cathedral on that tiny island in the center of paris. we soon see the flashing lights. police still keeping everyone aw. t we hav been iited he byd nel chargee freh president to bu notre dame. >> good morning. >> reporter: good morning. good to see you. >> nice to see you. thank you for coming to paris. >> reporter: thank you for having be a part of. and you have been tasked with, well, some would say the impossible. >> nothing is impossible to a french general. >> reporter: the workers here wear protective suits and masks. 400 tons of lead were lost in that fire. >> thank you very much. >> reporter: he takes us in, and soon we see the charred stones. >> stones which are coming from the vault. here. >> reporter: these are the stones that came in from the roof of the cathedral. >> yes.

>> reporter: stones from the 12th century, each with a number, revealing precisely where they once were. >> this is wood of the top part of the spire. >> reporter: this is the top of the spire right here?iewod tnse roof. that was the moment the world gasped in horror. >> yes. it is the moment. >> reporter: we stand in the shadow of the cathedral's roof. we could see the rainshe robot. because of the danger. >> because peoplee the lives of the workers. >> this is just remarkable that this was saved. >> reporter: the stained glass. the giant rose windows survive. 42 feet across. >> they call them the rose windows. >> reporter: rose windows. there were fears the lead in the glass might have melted.

it did not. and there was another question so many have asked. what about the organ? through this small doorway we climbed the stairs to the upper level of the cathedral. >> wow. >> reporter: much of it untouched. one more doorway and we see it.. survived.ieve num o century. and the general says there is concern about possible damage. >> a lot of water. a lot of melt lead. >> reporter: they're going to be examining each of the pipes of this great organ to make sure they haven't been permanently damaged. but just to give you an idea you can't help but notice the ash and likely lead in here as well that remains, the soocaed part of the restoration that lies ahead. >> reporter: on top of the keys a layer of dust. and we notice the sheet music foreman on this restoration

project and the general point to the arches. >> there is no question that these arches built in the 12th century saved the cathedral. >> yes. >> reporter: but they add they must now pay attention to them. made of stone one foot thick, they held the walls of the cathedral together. but with much of the roof now destroyed they need to replace the weight that once sat at those arches to hold them down and hold the walls together. we were also given access to something taken off the roof just days before the fire. the 12 apostles, all part of the spire, saved simply because of timing. they will now be restored too. in back of the cathedral downstairs we had heard of something else. >> this is the pillar right here? >> yes. >> reporter: on that pillar once twuseod a statue of the virgin emary and he says he's about to give us a view of her not seen since the 14th century. we could now see into her eyes, something not possible because

of centeriuries up on that pill. >> no one has been able to look at it at eye level until this moment. >> yeah. it is a privilege. >> reporter: so much has been saved here. >> it's really just an extraordinary sight. you can see the historical altar here in the cathedral is intact. it was saved here behind me. despite the fact that right over my shoulder you can see part of the spire here on the floor of the cathedral. and here you can see the choir completely intact. they'll just simply have to clean the wood. and of course this is the part of the cathedral that most people who travel from all over the world would know. the altar for mass is on the other side of me here. that was destroyed in the fire. and if you look far to the back of the church, to the top there where the organ is, one of the great stained glass windows survives. and now the people of france and the world wondering how soon our lady will be back. the french president has

suggested it could be done in five years. >> yes. the french president has rightly suggested that it could be done in five years. >> reporter: you believe it's possible? >> not only i believe it's possible but we will do it in five years. but we will not of course confuse speed and haste. >> reporter: and we asked about that early symbol of hope, the cross seen in the hours after the fire. and he takes us to the front of the church. >> wow. >> reporter: and there we see the cross, still standing. general, this is the cross that the world saw.ye s. the entire world saw the cross of godemo still rising in the cathedral. but that it was still -- >> still the cross. >> reporter: still intact. the cross still there and so much of the cathedral still standing. general, what do you make of the fact that this cathedral survived the french revolution,

it survived world war i, the german occupation, and it's still standing? >> and she will be standing again and again, defying the times. >> reporter: i'm david muir for "nightline" in paris. >> our thanks to david. and up next here, tapping into an alcohol-free lifestyle that might just raise your spirits. when i was diagnosed with breast cancer, there was no hesitation, i went straight to ctca. after my mastectomy, it was maddening because i felt part of my identity was being taken away. when you're able to restore what cancer's taken away, you see that transformation firsthand knowing that she had options that she could choose, helped restore hope. my team made me feel like a whole person again. cancer treatment centers of america. appointments available now. cbut their nutritional needs remain instinctual. that's why there's purina one true instinct.

without booze. here's abc's deborah roberts. eporter: it's the kin of party you don't want to miss. the music's pumping. the crowd jumping. except this is no ordinary night out because this party starts at the crack of dawn. this is daybreaker, where the buzz comes with a dose of mindfulness. and no booze. it's just one of a growing list of venues offering an alternative to knows choosing not to drink. they call themselves sober curious. 33-year-old josh hirsch, a former wine buyer, is one of them. the difference between sober curious and sobriety is what? >> the big difference is that people who are in recovery need to be in recovery. sober curious is you've noticed in your own life how drinking has impacted you and you've come to a point where i need to think about this. >> pervasive part of modern life, josh began questioning the

troubling side effects that come with being part of a drinking culture. it seems to be a neverending bender. >> last october i decided, i was like let me do november and december just no alcohol. and if i can do it during the holidays then i can do it anytime. so i did it as an experiment and i just was like oh, wow. it made such a difference. >> reporter: he heard about the sober curious movement through lifestyle journalist ruby warrington, who wrote a book by the same name after going through a similar journey. >> i came to drinking age with very much "sex and the city" as my backdrop. it was seen as part of being a fabulous modern emancipated woman who lived this glamorous city life to end every day with a cosmopolitan. and it was shocking to me how much my experience of good times or glamour or parties and socializing seemed to rely on alcohol. >> reporter: in her quest to confront a relationship with alcohol ruby discovered a

sobering reality. >> alcohol-related illnesses are the third cause of preventable deaths in the u.s. it definitely contributes to cancer, to alzheimer's, to heart disease. these are not things that we often hear about. >> reporter: 1 in 12 americans suffer from alcoholism. and according to the cdc, rates of cirrhosis are rising dramatically. ruby says it was a wake-up call to spread the sober curious message. >> anybody who's questioning their drinking is sober curious in my book. you don't have to be completely abstinent from alcohol. it requirehinking of yourself as a non-drinker as your kind of baseline and then from there choosing very selectively when you might engage in having a drink. >> reporter: for those questioning the effect of alcohol in their lives, listen bar has provided a non-alcoholic alternative. >> i'm having a spicy drink as well. it's delicious. it's got jalapenos in it. >> reporter: it looks like the average bar, but looks can be deceiving. for the folks here there's no hangover to worry about in the morning. >> we're here because it's an

alcohol-free bar. make as is a very t drink. yoseno one' tnk y'rendvs a typical bar, and the only t thing that's different is that those drinks don't have any alcohol in them. >> reporter: you won't find any syrupy shirley temples here. >> our drinks are very grownup and, you know, complex. this one is the actual sunshine. it's got mango and seedless and euphorics and pilot combucha. this one is the dollar slice. it's sort of our spicy bloody mary. >> and customers seem to approve. >> it tastes like a complex sort of gin and tonic but there's no alcohol at all. >> i just feel like alcohol is pushed at us all the time.

so just like stepping away from that feels very nice. >> i'm surprised that there are sober bars. >> this has really only happened in the past year, and i think these products and these services for people who are like hey, i want to go to a bar, i want to be social but i don't want to drink water all night, you know? >> reporter: you may have heard of dry january. now a concept that some are extending all year. in fact, a recent survey found that 1/3 of people want to drink less. >> it's more than a trend. you can see it as partly as an extension of the wellness revolution that we're seeing. >> reporter: and the beverage industry is getting in on the action. from vanada, a non-alcoholic sparkling rose, to seedless, a non-alcoholic spirit. even global brands like heineken now offering a non-alcoholic beer. tonight josh and boyfriend adam are getting ready for a night out on the town. for the sober curious it's not always easy. >> so many social activities are centered around alcohol. so i think there really is an

underlying sort of craving for these other spaces. >> reporter: they're headed to getaway, an alcohol-free bar that offers t much-needed haven. >> i'm interested in the sort of vibe they're going to set since it's like a sober bar, is it going to feel the same as a regular bar or is it going to have a different feel? >> reporter: getaway's founder sam thonis wanted to open a space where he could hang with his brother, a recovering alcoholic. >> we've been pretty deliberate about not calling ourselves a sober bar. we are a bar. we don't have alcohol. that's kind of the beginning and end of the pitch. >> reporter: the final consensus? >> we stayed longer than we planned. poriteob curious hy

crowd. >> i watch how alcohol tends to be a necessary binder for people in order to feel comfortable. daybreaker and so many other experiences like this are out there for people to be able to open themselves up without that lubricant. >> whoo! >> reporter: this group trading in their bottomless brunch for beats. >> the fact that daybreaker offers so much fun with other people who feel the same way and you can just let loose and be crazy without any alcohol in this case is a lot of fun, and it's healthy feetnghatnydy would want.ce and connection. i mean, wow, that's a big for. >> these are all things i've experienced in my life and all things i've seen other people in my life from family members to my husband to my friends to people in my wider community

reporting experiencing these benefits. i truly do believe that you can't possibly know how much of an impact not drinking is going to have on your life until you stop, until you get sober curious and see for yourself. >> as for josh -- >> i think mentally and emotionally i feel much better. i feel very clear-minded, you know, in terms of like making decisions. and i haven't been hung over. >> it feels so good. >> to your health. >> thank you so much. >> i'm famous for saying this is so good, if you just put a little something in here it would be even better. so i've got a ways to go. >> reporter: for "nightline" i'm deborah roberts in new york. >> our thanks to deborah coming up next here. sitting down with howard its in. what he ho say about the man he calls perhaps
