It is a building often overshadowed by the grandness of the Cathedral Basilica, but a unique structure in it's own right.
"It was built in the 60's and it was the original chancery of the Archdiocese of St. Louis," Brian Thouvenot, the Chief Development Officer of Catholic Charities of Saint Louis points out.
"It is a circle. So one you won't get lost and there's no such thing as a private conversation because the sound travels around the curved wall."
Thouvenot is also our tour guide.
"So that stained glass window was inside the chapel at our previous facility."
It is a place with stained glass throughout.
"So when it's bright and sunny out you see light shining in in various ways."
The real beauty, however, is the work the organization does in the community.
"It's all about people in need. It doesn't matter who you are, if you're catholic, non-catholic, we're just here to help our neighbors in need," Thouvenot explains.
The mission has been the same since 1912 to serve the poor and vulnerable and they do that through eight different organizations helping do everything from feed the hungry to putting a roofs over heads.
"Most Catholic Charity organizations are one organization with multiple programs we're a federation of agencies that then administer the programs."
Of course lending a helping hand often requires money.
"So we do have to raise money for the central office and mostly that comes through individual donations."
The staff will help guide people to things they are passion about.
"If someone comes to Catholic Charities and really has an affinity for the homeless we're going to connect you to St. Patrick Center. The same way if you have an affinity for adoption and foster care services we're going to connect you to Good Shepard Children and Family Services."
So the building might be retro, but work this organization is doing is as relevant as ever.
