Old Port Square reimagines a four-acre site as a new urban heart for Portland featuring residences, retail, restaurants, hotels, offices, parking, and inviting public spaces. Situated at the district’s center, a mixed-use residential and hospitality tower at 45 Union Street will add to Portland’s skyline with a design inspired by Maine’s historic lighthouses. Through its materials and details, the 30-storey, 380-foot-tall building resonates with Old Port’s historic architecture and creates public spaces atop the tower with views of the White Mountains, Casco Bay, and beyond.
