Grand Central Terminal in New York City is perhaps best known for the cerulean blue and gold astronomical mural that graces the majestic, vaulted ceiling of the Main Concourse.

The terminal opened on Feb. 2, 1913. In honor of its centennial the Metropolitan Transit Authority (MTA) commissioned Billy Collins, former poet laureate of the United States, to write a tribute.

The mystery of the human relationship to the cosmos is evoked in his poem.

GRAND CENTRAL

The city orbits around eight million

centers of the universe

and turns around the golden clock

at the still point of this place.

Lift up your eyes from the moving

hive

and you will see time circling

under a vault of stars and know

just when and where you are.

Billy Collins

Poetry in Motion, a program of the MTA, has placed this poem in subway trains for riders to contemplate.

Living so close to Grand Central, we might take for granted this place that is one of the most popular tourist destinations in the world. A schedule of upcoming centennial events adds to the lure of visiting the terminal.

Billy Collins, among other poets and musicians, will be featured on April 10.
