Brooklynites marveled once again at the beautiful architecture of the former Williamsburg Savings Bank at One Hanson Place, when the building’s historic bank hall and vault were re-opened on Thursday as a brand new event space called Skylight One Hanson.

Most of the space in the building has been converted into 179 luxury condominiums, but the infrastructure remains intact, boasting the same marble floors, carved teller stations, and a 40-foot mosaic of New York as a Dutch colony.

“There is a real demand for special event venues located within architectural monuments, both in Manhattan and in Brooklyn,” said Jennifer Blumin, president of the Skylight Group. “The space’s historical ties to the community make Skylight One Hanson the ideal setting to bring New York’s event industry together with the best of Brooklyn’s local vendors.”

Partygoers enjoyed drinks, hors d’ouevres and desserts, including a gigantic building-shaped cake designed by popular Brooklyn baker Cakeman Raven.

The event was hosted to highlight the borough’s potential to be the home of high-end event venues, starting with the 15,000-square-foot Skylight One Hanson.

“The Rainbow Room can’t hold a candle. Grand Central Station, you know what I’m going to say: ‘Forget about it!’” said Brooklyn Borough President Marty Markowitz. He added jokingly, “Plus, it’s conveniently located for guests arriving from the ‘outer borough’ of Manhattan — and I guarantee that once they see all that Brooklyn has to offer, some of them won’t be going back!”
