HARTFORD, Conn. (WTNH) — Friday is National Superheroes Day — a day to celebrate people who exhibit strength and do good deeds, whether they wear a cape or not.

Connecticut Children’s Hospital in Hartford held a superhero-themed event on Friday, as the hospital broke ground on a new, eight-story clinical tower. Caped crusaders and the earth’s mightiest heroes were in attendance.

The highly anticipated groundbreaking was touted as the most ambitious expansion in the history of the hospital, and superheroes were called on to be a part of the expansion.

The new, eight-story tower will connect to connecticut children’s existing medical center in the capital city. It will feature an array of services, including 50 NICU beds.

“Today we’ll break ground on a building and a brighter future for the children in our region and the families around the world,” said Jim Shmerling, CEO of Connecticut Children’s Medical Center. “A place where we’ll care for the tiniest patients in the neonatal intensive care unit. Where a fetus with significant anomalies can be diagnosed and operated on in utero. One of only a handful of hospitals in the country with the talent and resources to perform such state-of-the-art care.”

Friday marked the 10th anniversary of Superhero Day, a day that brings joy and smiles to the young patients.
