One spark is a place for creators to show off their projects-- and one project you'll find downtown is the secret bank vault at the old Atlantic National Bank. Normally the public can only see the piece of history on Tuesday and Thursday mornings because of it's location. But if you come to One Spark you'll get a chance to see it everyday until Sunday. Channel 4's Ashley Mitchem got a sneak peek and tells us a little of the project's history. Let's go back out LIVE to Crystal and Ashley at MOCA - they talked to the creators behind the idea. 3 3 If you walk along Forsyth Street and look at the old Atlantic National Bank you would probably never know there are underground bank tunnels just below.One of them features an underground safe from the 1900s.I went underground with Jacksonville Walking Tours to see the safe and to find out why they decided to feature this at One Spark. 3 00-10:37-:42GARY SASS, JACKSONVILLE WALKING TOURS 21:51 This is going to be the coolest place to come because you're going to be underground and you're going to see something no one else has you're going to see a part of history here in downtown Gary Sass plays the part well as he took us back to another time...this underground vault originates to the 1900's .It was last used as a safe in the 50s....in the 60's in was a fall out shelter and in the 70's it was used as storage. But now the folks at Jacksonville Walking Tours are working to transform this vault back to it's original look.20:02 This should be restored because heritage tourism is so important to Jacksonville- it's really a small example About three years ago they started to host tours underground .Tours are normally only offered on Tuesdays and Thursday, but now, you can go underground everday throughout One Spark. They are trying to generate local interest in heritage tourism.19:46 Our project which is a restoration of this old bank vault here so I want to show them what it is we are doing here and show them the secret tunnel tour The bank was built in 1909 and at the time was the tallest building in Florida.20:10 if you think about it it's really our identity this is our history the banking history here in Jacksonville 3 3 The Jacksonville Walking Tours will do Secret Tunnel and bank vault Tours every 5 minutes during the One Spark festival.From Downtown AM C4 TLS.
