Summary

It was designed by landscape architect John O. Simonds and opened in 1955, making it the first modern urban park in the United States. The park covers 1.37 acres and features a reflecting pool, a cascading fountain, and winding pathways.

One of the good reasons to visit Mellon Square is to experience its unique blend of modern and classic design. The park's mid-century modern aesthetic has been preserved over the years, and visitors can still see elements like the original benches and light fixtures. Additionally, the park underwent a $10 million renovation in 2014 that added new amenities like a café and updated infrastructure.

Specific points of interest to see in Mellon Square include the "Silver Clouds" installation by artist Andy Warhol, which features hundreds of silver balloons suspended from the ceiling of the park's pavilion. There's also a playground for kids, a dog park, and numerous benches and tables for picnicking.

One interesting fact about Mellon Square is that it was built on top of a formerly bustling commercial district that was demolished in the 1950s to make way for the park. Today, the park is surrounded by numerous office buildings and is a popular spot for lunch breaks.

The best time of year to visit Mellon Square is in the spring or summer when the weather is warm and the park is in full bloom. However, visitors can also enjoy the park during the fall and winter months when the reflecting pool is transformed into an ice skating rink.

Overall, Mellon Square is a must-see destination for anyone visiting Pittsburgh. Its unique blend of modern and classic design, interesting history, and numerous amenities make it a popular spot for locals and tourists alike.
