Centennial Park is one of Nashville's premier parks and features the iconic Parthenon. Located inside the Parthenon is an art gallery which includes a complete replica of Athena herself! Centennial Park is also home to a one-mile walking tail, Lake Watauga, an arts activity center, a beautiful sunken garden, and a band shell.
It is also home to Musician's Corner (https://musicianscornernashville.com/) a free outdoor concert hosted mainly in the summer and early fall. It's an excellent way to participate in Nashville as the locals do.
