High Quality Content by WIKIPEDIA articles! 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. This led to several years of dispute between the developers trying to block construction of each others` towers.
