No visit to ONE KING WEST is complete without stepping down the sweeping central staircase to the original underground bank vault. Built directly into the bedrock in 1913, the vault features an incredible 4-foot thick steel door that weighs 40 tonnes, yet can nonetheless be moved with a single finger. During construction, the gargantuan door was hauled up Yonge Street from the harbour by a team of 18 horses. Today the vault and surrounding event space is one of the hotel's most exciting and rare venues. A must see and a must experience!
