The park was established in 1943, on the grounds of the former estate of Richard B. Mellon. His was the largest mansion in Pittsburgh. The mansion was built by Italian immigrants from New Kensington, PA under the direction of Monsignor Nicola Fusco. These industrious men then built the monumental Mount St. Peter Church inNew Kensington which still stands and functions to this day from the materials of the Mellon Mansion. The gardens were originally designed in 1912 by Alden and Harlow. Several other architects added their own touch to the landscape including the Olmsted Brothers and some seventeen yearsafter the garden began, Vitale and Geiffert. After Mellon's sixty-room home was brought down during World War II, most of the garden still remained and was transformed into a city park known now as Mellon Park. The park also contains the Phipps Garden Center and Pittsburgh Center for the Arts.
The Walled Garden
The Walled Garden is surrounded by walls of brick and limestone and one of Gothic design. The garden's fourth wall was part of the Mellon mansion before its demolition in the 1940s. A fountain stands between the garden and the rest of the park. Vitale and Geiffert were behind the planning of this garden. The Mellon Park Project wanted to create a memorial in memory of Ann Katherine Seamans, who frequented the Walled Garden repeatedly after being introduced to it in kindergarten. Janet Zweig, an artist chosen by the project team, turned the floor of the garden into an exact replica of the sky in Pittsburgh on the day Ann was born. There are 150 stars and each is a light in the ground and includes an inscription about it. It is possible to sponsor a star and make a donation. LaQuatra Bonci Associates was responsible for the planning and supervising of the garden's redemption. The park was reopened on June 12, 2010.
