The Residences at The Ritz-Carlton is a luxury residential skyscraper in Center City in Philadelphia, Pennsylvania. At 518 feet (158 m), the 48-story skyscraper is the tenth-tallest building in Philadelphia, and the tallest residential tower in the city. The building was erected on the former site of One Meridian Plaza which was seriously damaged by a deadly fire in 1991. One Meridian Plaza was demolished in 1999 and the property was sold by E/R Partners to the Arden Group the next year. Development of the site by the Arden Group, which owns the adjacent Ritz-Carlton Philadelphia, was delayed for years as a result of a feud with rival developer Mariner Commercial Properties. Mariner owned the property 1441 Chestnut Street, which sits south of the Residences at The Ritz-Carlton site and intends to build its own residential tower. The feud began after Arden Group's lead partner Craig Spencer blocked approval of 1441 Chestnut Street because he felt the tower's design would be detrimental to the planned Residences at The Ritz-Carlton tower.
