For more than 40 years, Century 21′s flagship store at 22 Cortlandt St. has been a retail magnet for tourists and residents seeking discounts on designer fashions and brand name merchandise.

Across from the construction site of the new World Trade Center buildings and the National September 11 Memorial & Museum, Century 21 will be expanding its space by more than 99,000 square feet. It will also be renovating its existing 150,000 square feet.
